waw

you are left handed

btw thanks it help me so much in Current Popular IT assignment

[curbro48]

Patrick: You're the poo. Your example made more sense to me than any of the others I watched. Thank you so much for your help. I'm subscribing.

[869749856]

I have an exam on this in four hours, lol.

[chazmazzer]

Thank you. Thank you so much. I have an exam tomorrow and this was impossible for me because I was supposed to be teaching myself! Now to learn the rest of the module... :[

[darrenshan76]

@chazmazzer I'm in the same position but mine's tomorrow! AQA Decision Maths Module 1, 9.30AM, UK! BUMMER!

To @patrickJMT Thank you! Great help, great pace! You're awesome. :D

[richyrich356]

<3

[superman3621]

@patrickJMT can you do a video where the constraints have a equal sign? i don't understand empty feasible regions. Please and thank you :)

[2DancinQueen3]

Thankyou so much! I was working on my math project and everywhere they tried to explain this, it made no sense. Thanks again.

[MyByzantine]

I like this; Thank you

[luckygoleah]

My math final is in 2 hours and I could not figure this out! Thank you, you saved my grade!

[fruittart4eva]

thankyou!

[WollyTheCow]

Holyyy Coooowwwww my scores in my quizzes and Long tests got higher because of your tutorials!!! THANK YOU!!!! I LOVE YOU MAN!!!

[chids4christ]

@patrickJMT you learnt maths on mars hey? coz your lessons are HOT!!!!!

[BigBangLover1220]

thank you soooo much!!!! my teacher does not know how to teach and this just helped me a bunch!!!! :D

you are the best!!!!

and thanks again :)))

[BigBangLover1220]

thank you soooo much!!!! my teacher does not know how to teach and this just helped me a bunch!!!! :D

you are the best!!!!

and thanks again :)))

[00000Milkshake]

Excellent mate. Very helpful for my Decision Maths A level in England tyvm!

[ether0076]

You know that feeling when you suddenly begin to understand something you haven't understood for five days straight?

I love you right now. Seriously.

[chemo100001]

thanks the lesson was good either way better than my teacher i still got the point thanks + who doesn't make mistakes : )



[danielamorillo]

what a great explanation and run through thank you sooooooooo much , i have been having the worst time with linear programming and you explained it beautifully and simply ,much appreciated!!!!!!!

[Daliamaya3211]

this is awsome now i dont have to keep asking my teacher for help! wahaha :)

yeah i understand the concept better THANKS! n_n

[VladimirAteAVampire]

You have just saved my bacon...I'm not even joking.

This was going to be the horror of Decision Maths A level for me....

You can't even imagine how much love I have for you right now. I might even pass O.o

[ZakAtk123]

Im going to keep it simple, thank you!

[bdorn33]

Helped me on my Algebra 2 take home test. Your a grade saver. You explain way better then my teacher!

[matrixkernel]

Why is it true that the "corner points" will yield the extreme values of the profit?

[rochelle178]

@matrixkernel dantzig theorem!

[ThePearlandiamond]

@merucks Hahahahahahah

[OldChikity]

LEFTY!

[Hardstyl3r17]

this is really well explained, comes really in hand since have to do math test about this to get my diploma ^^

[SpartanDara117]

What a truly fantastic video. I have an Alg2 Honors test tomorrow, and this was the only thing i didn't get from my chapter. Again, thanks a bunch!!

[mathewrokz]

awww this is amazing thanks for the help :)

[SuperDylzo]

Thank You so much man, I have a text book at home devoted to this stuff but it doesn't show how to enumerate the corner points with algebra! I'm glad someone out there has gone to the trouble. Thanks again!!

[d1a2n3i5e8l]

Thank you.

[YouBetterDoBetter]

THANK YOU SO MUCH!

[AsianC00kies]

life saver. explained things my teacher couldn't. thank you so much

[Gildo202]

Thank you for you for this video.. You could explain something my high school teacher couldn't ..

[MrLeegene]

Thank you for this great video. This really helped me with my Algebra 2 hw. You explained it better than my teacher who made this seem difficult when it's not.

[demsgaz]

so, the answer are 80 acres for corn and 160 for oats. ain't it?

[canadianslumbaparty]

THANK YOU.

[sexynessisandrew]

Mann, at least you annotated your mistake, it doesnt matter to me! at least i know what to do :)

[RahulsApps]

I have a question because I couldn't hear the video well enough. How do know which points are the vertices which you use to find the min and the max?

[chi2uk]

Wow...i've come accross LP for 2 years and i'm just understanding it. Thank you so much Patrick. You're the best....a life saver

[rlclah32]

Eventhough you had mistakes, you were better explaining than my math instructor who sucks at it. Thanks for helping prep my math exam. :)

[kianmay96]

dang bro try to hop off this guy is a beast at math and the best thanks man you really help me time to get an A on my quiz!

[doodl3bugg13]

Does it always turn out to be a quad? I did a problem in my book and I got a triangle for the space.

[OmegaF77]

Thanks a lot for this video. It really helped me in my Algebra 2 assignment!!! :D

[McWeslyF1]

regardless of the tiny mistake, that is an excellent and thorough explanation! Thanks man, you just helped a person on his homework! (Algebra 2)

[patrickJMT]

@McWeslyF1 mistakes happen, only trolls hyperfocus on them! thanks for the kind words : )

[lilpimpen7]

@patrickJMT I just hope you know that I love you.

[patrickJMT]

@lilpimpen7 : )

[poogeasaurus]

Thank you so much for these videos! You are SO helpful, and you've eased my homework panic in study halls!

[MrUgonna531]

Wow! Just learned in 11 mins what my teacher failed to teach me in a week, you make it so simpler, thank you.

[nextblain]

lol i think the smart thing to do is watch more patricks videos and subscribe him :D

(u saved my ass patrick, i love ur vids!!)

[Tkdkid9]

optimization problems for non-calculus students...awesome!!! I've taken all of the calculus's and I've never actually done one of these particular problems before...

[egunje01]

could someone pls solve this problem? i have issues with it thanks Farmer has 240 acres of land. He can plant corn and oats. When planting corn, his profit is 40 USD per acre of corn. When planting oats, his profit is 30 USD per acre of oats. Farmer has 320 hours of labor available. Corn takes 2 hours of labor per acre, oats requires 1 hour of labor per acre. Use the linear programming approach. How many acres of each (corn and oats) should farmer plant in order to maximize his profit?

[krtkmtuswmy]

Well put. Any book recommendations for LP?

[merucks]

wow! I guess that also explains why our math scores are so low. Video tells me 3200 + 4800 = 7000 and then a comment from danjhall tells me it's 8000. the correct answer is 9000!!!!! I only wish I were accountant...other than that, good explanation!

[patrickJMT]

@merucks you make fun of people making mistakes and you do the same thing. classic.

[VDiabloV1]

@merucks it's 8000....bet you feel stupid

[himguyman]

@merucks it is 8000.

[himguyman]

Wow. Im so thankful for youtube. Teachers think they can get away with the old excuse for not teaching by saying that you are honors students and shouldn't need the full demonstration.

[lolcandii]

@merucks ok get alife my dude.....one mistake....come on.....loser

[QuintinRaptorBotes]

@merucks hahahahahahahahaha 9000 is it?

[samuil5]

@merucks hey bro guess what its 8000 you are worng!!! haha

[astrojg0]

@merucks it is 8000 

[lokiuish]

@merucks 3200+4800=8000. Accountant, hahaha, nice joke! 

[destroyerxx6]

@merucks fucking idiot

[scanz1ar]

@merucks if you can show me how 3200 + 4800 = 9000, i'll kill myself

[iAmACrappyAmvMaker]

@merucks lol dumbass

[jamesdaviesliverpool]

just wanted to say thanks for all your videos

[jaensda1]

haha aww man that must have been embarrassing the mistake at the end, but it could have happened to anyone. thanks so much! this explanation defs helps a lot :)

[MetaIhead89]

great video, thanks!! except the mistake at the end lol

[muhNadeeem]

Thanks

[flyingbeagles]

WOAH random ad started playing when u were explaining corner points LOL

[ccisbeast]

This video ensures that nobody meddles with the primal forces of nature.

[danjhall1]

3200 + 4800 is 8000 not 7000 so surely you want 80 acres of corn and 160 acres of oats?

[ff7masta]

@danjhall1 There was an annotation that corrected that mistake.

It is indeed (80,160).

[random255]

I'm talking math as an online course at the university level, and watching this video is > reading the chapter. Thanks for a quick 11 minute lesson!

[mysoukouss]

thanks Patrick. nice review

[maryslittlelamb08]

Life Saver! Thank you sooo much!

[VTDragon6]

thank you for teaching me what my teacher didnt :)

[j009aguar13]

thanks a lot this was very helpful. I was just wondering, do you do this for science too? I mean, things like stoichiometry and equation balancing?

[comskey420]

thanks !! well explained very helpfull !!

[rahadahmed]

You've made this sooooooooo much easier than what I thought of linear programming initially! :D

[jeff177177]

press ctrl+ w to skip adverts

[elemperador01]

thank you very much for your video!

[R0ckinR0ughley]

Great lesson, thanks!

[russellsolid]

lol i wudnt of relized the mistake if u didnt point it out

[icefoxx001]

lmao @ the mistake!! this is great, i love linear programming now. that was easy.

[usernamarefull]

your voice is annoying :( but you teach really good!

[wellooeeeee]

who the hell is make linear programming .. im gonna fuck his mom

he fucking roin my average

fuck you linear programming guy

[ff7masta]

@wellooeeeee that guy ensures that you have food on yor plate every night asshole.

[5B80JW]

What if there comes a situation wherein the lines don't intersect?

[code3kc]

For the third time this semester, you will be the reason I pass my test tomorrow. For the life of me I couldn't figure out how to find the point where the lines intersect. But after this, it all clicked! Thanks very much.

[raymondbc15]

holy shit i understand this more after watching this thanks man

[sheeeshah]

at (80,160) P=3200+4800=8000

that will make it the Max.

[Riflemanm16a2]

Wow, three advertisements on an 11 minute video.

[evercoop]

@Riflemanm16a2 its actually an 11.18333 (3 is reocurring) video.

[SupremePerdomo]

I understand this now! Thank you, you were very helpful.

(Aware of your final mistake but I'm sure you know already.) Once again, thank you!

[rl520]

thx, for this video! it made me get into to my "math mode" and be able to solve a problem!

[lealsprinter]

Major fail on final answer :(

I would also want to say that the maker of this video is lazy. Instead of redoing the video to make it seemless, they add a few comments at the end. Its understandable to make mistakes on the fly, but not when you post up a video! Redo!

[svtuition]

Great lecture

[GlowMagik]

Question: my lecturer said you don't need to draw a graph to solve an LP problem like this. So how would you identify the other two points of the boundary i.e (0 , 240) and (160 , 0), without actually drawing the graph?

[GlowMagik]

@GlowMagik Thinking about it, i guess you could work through the constraints - dividing x or y by the time available, and the lowest x result would be your boundary point on the x axis and the lowest y result on the y axis. Is that correct?

[sharksavage]

6 people dont like maths

[wagooli]

Sorry to sound pendativ but 3200+4800=8000 hence being the most profitable otherwise good stuff

[GlowMagik]

Thank you :)

[adriboy88]

Thankyou so much! I need this for my FSMQ.

[FremaAwuku]

thanks!

[colliesz]

Clears my confusion of what the heck my prof wants from linear programming. This is good, thank you so much.

[nightshadexoxo]

thank you soooooo much! :3

my teacher is new and has a hard time explaining: he doesn't say how to do the problem: he makes us come up with equations and ussally the equations and the whole problem turn out wrong and then I can't understand the way your acctually supposed to do it! <sorry if that was hard to understand

tl;dr thx! my techers sucks and u rlly helped!!! xD

[hpeselyk]

In my experience, teachers are easy to blame. I'm gradee 11 and had 3 different teachers for Math10-12, so means different kind of teaching. Its the student's responsibility to understand, and if they don't, ask their teachers. Ask your teacher questions after school if even possible. To go over question in your homework that you don't get.

[patrickJMT]

@hpeselyk always easier to blame someone else than to take any personal responsibility.

[hpeselyk]

@patrickJMT yeah, i know, i just feel sorry for the teachers that's getting smack at, they are disappointed to if the students failed, they want you to do your best.

Anyways, good videos :). The calculus one

[joepglass]

@patrickJMT How is that any different than a teacher blaming the student/parent??

[patrickJMT]

@joepglass not sure what you mean

[joepglass]

@patrickJMT Teachers blame the students and parents. Parents blame the teachers. They both fail and share in the problem. Public Education is the problem in my opinion. Just today, a teacher was arrested for closing the laptop of a student causing a ruckus. In a private school, that does not happen. Give control back to the teachers, it is not a perfect system, but this system has failed. Time for a major change, imo.

[patrickJMT]

@joepglass there is a lot of blame to go around, but it is ultimately the students issue to learn. one has to learn to teach one's own self. if one can not learn something (or at least try to) on his/her own, they are doomed in life to be a drone. so many people want to be spoon fed everything: just show me how to do the problem, do not make me think about it <----- i have heard this so many times, both as a student from other students in class and from students when i taught.

[joepglass]

@patrickJMT "but it is ultimately the students issue to learn."

No, it is the teachers JOB to teach them. If they cannot "teach" the student, they have failed at the job. That happens all the time and is unavoidable. Some people refuse to learn, that is a sad fact of life. But we need to understand that and, try to come up with a better system to teach them. But we will not make any changes because teachers are scared to lose a job they have failed at doing.

[Nautilus1972]

@joepglass Blame the Fed. It's the Fed.

[MrSuckerz]

@hpeselyk Im doing year 8 extension math and over my coarse I am covering this. Year 11 really.

[firesniper23]

I have a Problem that is i must sell trashcans to different schools and they both have different prices and minimums and maximums so would is be x + y > Mini1 + Mini2?

[bathinbapes]

I luv u no homo b/c of u I finally understand this b/c my ALG 2 teacher can't teach

[stooncol619]

U R AMAZING THANXXXXXXX

PLEASE KEEP IT LIKE THAT

THANX

[19962charlie]

Im in 8th grade and doing this! :L my teacher is crazy

[micahclayrussell]

@19962charlie how old r u?

[19962charlie]

@micahclayrussell 14 :L

[micahclayrussell]

@19962charlie me 2 and im doing this too

[decies11]

Excellent tutorial!

[CarlosS0808]

Cus ur looking for the max profit

[kamatanurag]

thank u sir! from the bottom of my heart!

[wc1hater]

Hi, I have a question... how exactly does this work?

Or rather, why couldn't some random point in the shaded region have been chosen? How do we know one of the vertexes would give us the most profit?

[michaeljacksoncoco]

expain that for the good of all of us who once in their lives though that matematics.,algebra etc are so complicated but useless, even nowdays(LIKE SOME ALGEBRA I have seem many other topics that I can not possibly discover for what they could be useful for real life or other things...lastly great video, no many people take the time to teach for free and post videos...

[user1maximus]

patrickJMT I love you because you made an easy-to-understand awesome video, and most of all because you're left-handed XD

[dudeB15]

thank you so much, i would marry you, but im not gay

[Shez10991]

Whoever made this video needs to be given a medal. Thank you! legenddddd

[mick5000x]

now there's advertisements on educational videos. wow, who were the stupid lawyers that forced youtube to do advertisements, yet wmg and other groups won't let us use their music. kind of a ripoff don't you think?

great video btw, i finally understood my homework.

[CAYOSERJIO]

Hi Pattrick thanks so muh ,, just woder what if I have for example x,w,y,z or more inequalities?? thanks...

[bestdyush09]

continuation...

ice cream cone for $2 and each frozen yogurt cone for $1, what is the maximum amount they can expect to make?

please please! i really need to get this stuff! please help me! thank you so much!

[bestdyush09]

Hi, is it okay if you help me with this problem? coz I was gone when my teacher taught this and i just don't get this at all when he explained it!

the members of the junior class are selling ice cream and frozen yogurt cones in the school cafeteria to raise money for prom. the students have enoug ice cream for 50 cones and enough frozen yogurt for 80 cones. they plan on selling atleast 20 more yogurtcones than ice cream cones. they have 120 cones available. if they plan to sell each ice cream

[exceedtheman]

Can someone help me with this problem...

Person A can paint a wall in 6 hours and B can do it in 4 and C does it only in 2 hours. If they work together how long will it take?

[stinger2500]

got a quantitative marketing exam in 1 hr in 30 min and u just saved my ass :D didn't study for it yet :P God Bless open book exams ^^

[stinger2500]

[ScumbagRS5]

My teacher is Asian and even though she has a hard accent i feel that she is a way better teacher than most of my other teachers last semester. You can blame the teacher but lets not forget that in today's world, we can get a hold of resources(internet, library) much easily. Another problem with education today is that students are working full-time or part-time and going to school full-time. It is difficult to make a schedule that satisfies both equally.

[patrickJMT]

@ScumbagRS5 i worked 40 hours a week in a restaurant and took 18 hours many semesters, so tell me all about it. no free rides here. and complaining about an accent of a teacher in college is just silly (not that you are complaining, but for those who do) . school is hard, yes. work is hard, yes. but so many in the world have it so much worse i just always thought: what do i really have to bitch and cry about? answer: nothing.

[ScumbagRS5]

@patrickJMT Yes thats correct but my point is that no one learns on the same level. A friend of mine works about 40 hours but he is a student that gets B's and C's. Me on the other hand could not be satisfied with that. I always aim for the A. For that reason we can't blame the school systems. Although there are some teachers that don't teach and rather talk about their life experiences well there is always the textbook or research on the internet to help us study and learn.

[ScumbagRS5]

@patrickJMT So basically we should learn how to teach ourselves. Read the textbook and seek other help. My other point is that people complain about their teachers but instead of complaining there are things they can do to help themselves. People should be self taught. Read the textbook with an open-mind and learn to appreciate the material by doing research. But again not many people have the time because of work. Some jobs are more exhaustive than others & not everyone learns on the same level

[michaeljacksoncoco]

@patrickJMT I admire people like you(do not underestand how a MIT student was working in a restaurant, it is not suppose at least the have wel off parents, loans etc , may be better tha here in NZ ), I guess you are looking forward to get a job where you can apply what you learn in which few have that level, and on the way to earn some good money offcourse(fear enough), I always have been interested in what can I jobs or real projects can you do with such an useful subject like this, can you

[stamaxo]

I love you man

[justinbellful]

Some birds can not fly in, Asian busizz4me.info

[n3wbiedoc]

thnx man, I do this everytime when I play myfreefarm :P

[montealegre5]

Understood...but 3200 + 4800 is NOT/NOT 7,000. The choice of x=80 and y=160 is still correct. Just a typo.

[patrickJMT]

@montealegre5 good to see that no one reads the annotations i put in, or the 100 other comments on this

[mim9988]

thx teacher, so good that, i couldn't stop commenting on youtube for the first time .

[DeathMetalMikey]

THANNNNK YOOOUUU!!

[littleroots]

I wouldn't say the students are lazy... I would say there's a lack of effective teaching. Some teachers expects students to understand without explanation

[soccer1dude5]

@littleroots thats exactly like my teacher just with this right now, he showed us a couple problems and let us do some stuff, now were going into more complex problems, and he put us into groups in our class with at least 1 math team member, who has done a ton of these already and understand all of them. Probably more than half of our class does not know how to do these because our teacher is pretty much having other students explain it to us, and they r not good at explaining at all...

[jagiter]

exams tomorrow. hope this is going to help. i saw ur video twice, once wen it was mid terms n now before exams.

first time i didnt totally get it. now i do. hope its gonna help!!!

[Dotanoobplatakis]

thnx man it works!!!!

[servant0of0god]

thank x man

[77gosabres]

Very impressive. You really know your math! This video helped me out immensely. I was stuck on a linear programming problem for my technical math w/ calculus class and this video gave me what I was missing. I was able to solve my problem and now have a better understanding of this type of problem. Thanks for posting!!

[reaching4sky]

jeez! silly mistake! but your explanation was great though!

[reaching4sky]

well, this sum is wrong, due to a simple mistake at the end. 4800+3200 = 8000 and not 7000. So the answer becomes that the farmer should plant 80 corn and 160 oats.!

[adrwolfie]

You're my new favorite ever. Thanks so much.

[HardstyleMenace]

Thank you.

[curryking95100]

Now I know how my friend gets high grades. She has you. Man your the best. I didnt get this over 45 minutes and what can I say amn. first tiem seeing your videos and will be seeing more. Thanks

[patrickJMT]

@curryking95100 glad u and your friend like the vids

[dzzylzzy73]

@curryking95100 hey that friend is me!! :D

[saara1311]

You are a life saver!!

[HabboLord101]

I WORSHIP AT YOUR FEET MY GREAT MATH MASTER ;)

[patrickJMT]

@HabboLord101 ha, no need for that.

[FLYHiGHx3]

Thank you for your videos! It helps me pass my class! ;)

[Maaaaaaaaaaaaaaartin]

So sad that you messed up the last part of an awesome explanation haha, no biggie great job really helped me!

[patrickJMT]

@Maaaaaaaaaaaaaaartin bleh, i do not care : ) it happens! i did the process correctly, and that is what is important ( -1 on patrick's test)

[SuperKnifeable]

YAY! This video helped me with my homework... ALOT! Thank you for doing this kind of stuff!

[algenis88]

I love you!!! :)

[SweetDinnerGuest]

Thanks for posting this. I was absent when this was taught.
