Properties of Logarithms - Everything You Need to Know!

[TrymyrT]

yo dawg, heard you like ln, so I put an ln in your ln, so you can raise to the e when you raise to the e

[phantasmaniacal]

hello @patrickJMT. i wanted to say thank you very much for your service. i have continuously returned to your videos and instruction. without your help, i might be getting by, but doing so far less easily. i sincerely hope that, in the words of mos def, you "be getting caked off your bookings." seriously though, your work is appreciated.

[MizzCrissy247]

Can someone link me a vid to express terms in natural logs? ! Pleaseeeeeee

[luisespinax]

You owe me log(10)1000 dollars!!!!!!

[353landry]

[AngusTaoHuang]

Your video and teaching is definitely useful and helpful, I'll continue watch it. :)

[Rabbit16O]

[patrickJMT]

@Rabbit16O factor it.

[kuduro321]

[123Moaed]

Thank you

[OliverTwist2013]

the videos on your website wont work on my computer :\ You're so helpful though! I wouldnt be passing my AP Precalc class without you! :)



[FpsFanaticAllAround]

Is this p slice

[syobteertskcab14]

just so u know u like saved my life lol thank you so much for putting these videos up i get it so much better when you teach it because my math teacher does not teach like at all !

[squiggles0v0]

answer for the second to last problem could have also been ((log2)/(log5))+4

[Saronaist]

u r the best. Both in your videos and comments. I can tell u have a sense of humour and funny too from your comments. Thank you so much. U r awesome Patrick. God bless you for helping us

[megametalpriest]

I pronounce ln(x) as "linux" :)

[animelovergal2002]

Your my favorite Math teacher or shall I say Tutor.

I am terrible at math (but) with all your videos, I will get better...

Every time I have problems, I always come to you to see if you can help through your videos.

What a headache, I have right now. ~ I don't think its from water 3 straight hours of your video. ~ Maybe I'm just worn-out from Drawing I class and the standing up we did the entire class

[AznS0ulja]

i was wondering how you would do it in 'swoop'?

[PoMPyroLoL]

I like how I'm paying for online courses at my school, and their method of teaching me is through your videos.

[patrickJMT]

@PoMPyroLoL ha, what school? i will tell them i want a fee : )

[woodybeast21]

hey your left-handed!

[alpinestars]

I want that watch in the ad

[minhdiszles]

the 1 dislike failed algebra..

[marius666]

God you are so awesome. So awesome. You will never realize how much you help us. 

[biotim]

Thank you so much. This really does help...

I teach chemistry and biology but constantly need to re-brush up on math. This helps tremendously, so.. Thank you. Keep on keeping on!

[MsErica98]

Hello @patrickJMT. How to solve for x in this logarithm? log 25 (base x) = -2

[RatchetSK]

is there any way to support u? like PayPal or that? coz this is damn awesome

[patrickJMT]

@RatchetSK if you visit my website (link on my profile page) and click a link to any video, a paypal donation pops up . : )

[dominator30000]

@patrickJMT I would pay for a subscription to your youtube. What do you do for a living regularly? Is this it?

[patrickJMT]

@dominator30000 making videos is now the primary source of my income, yes. and i have had people approach me with the idea of taking all of these videos off and making them a pay subscription but i will never do that. i like it being free so that anyone can watch.

[PhreshNess99]

@patrickJMT You're so awesome! I'm definitely donating! I just got an online banking account so I can do it myself =D

[patrickJMT]

@PhreshNess99 ha, nice :)

[thdominat0r]

do all logs go to heaven?

[julianaboulos]

just wondering about the last example..i don't understand how e comes in the equation? and what is the difference between Log and ln and e?

thank u for these videos!! they r really helpful!

[zooperist]

You are indeed the best!!!

[patrickJMT]

@zooperist awww, thanks ; )

[jasoncape]

Thanks a lot!!! :)))) 

[issavill111]

This really really helps!! I'm glad I've found you :D

[glitchnoise]

Hey why didn't you add the 10 to 3? 17:56

[halovir]

@glitchnoise we cant add 10 to 3. the 10 is a part of the log -> [log(10)] + (3)

[glitchnoise]

It only gets better after 11:00 more tutorials! What are your credentials btw?

[jakeb8493]

When you gave an example of the cancellation law at 15:10 , couldn't you just rewrite the equation in exponential form to get e^1/2 (a.k.a square root of e)?

[ButtInDa]

If I spent all day, 24h, watching your vids il KNOW everything my teachers TRY to teach me in a year :O. Thanks alot man! :)

[TheEricVolpe]

Just saying this summer i start AB calc so yea expect PM's about anything you don't have on your account x3

[KawasakiPlant]

I love math now! Thanks for the regents help!

[AEVautomatic]

faggy commercials

[BrownFlip7852]

subscribed! Helped me understand in 20 minutes what a whole term of work couldn't.

[downtownal400]

You, sir, are a savior to us math-challenged plebes. Me and all those like me, bow humbly before your mathematical brilliance and thank you profoundly for your generous teachings.

[jabberwiki]

log



[Kachii3]

You changed my life. I hated logs, and now, I think I'm in love with it. THANK YOU! Why couldn't you be my math 12 teacher?

[sundusxoxo]

YOU ARE THE BEST TEACHER EVERRRRR!! NO JOKE.

My teacher goes too fast, I get lost. You're bloody AWESOME.

THANKS :D

[AlmondOK]

Wow, this was simple, yet brilliant. You summarized two weeks of learning in twenty minutes! Thanks again, Pat!

[angelinbluejeans80]

Youre GOD! thanks a lot! :)

[Musiclo0ovee]

***** GREAT EXPLAIN ... THANKS PATRICK *****

[EFdesantiago]

You're the reason why I'm going to ace my precalculus final. Thanks a lot!

[sursk27]

I really hope your my math teacher in school :(

[stratusalso]

Hello, Patrick, I have been studying your video's for 12 weeks now. Been out of school for 25 years and just passed my college algebra test. Thanks

[DullahOblongata]

OMG! you said it "it might be confusing for the first time" my teacher started teaching it today and he's horrible and we have a major test on it in 2 days. Thanks to you though i get it now and i'm half way thru the video!

[MrVisuljak]

best math teacher on youtube, without a doubt

[patrickJMT]

@MrVisuljak thanks!

[MEESHisaBEAST]

@MrVisuljak best math teacher. period.

[TheBam008]

My teacher is good but he's been teaching me for two years and I learn more from you in an hour.

[vacholino]

Thank you, great video. Make a video on limit :)

[angleofthesoul]

ur the best damn teach in yt!!!!!!!!!

[patrickJMT]

@angleofthesoul thanks! : )

[warsilver99]

thank you so much

[dovegirl17]

Logarithms is the hardest part of math for me. Because Of You I am understanding it :)

[macias106]

keep up the good job mate!

[chrispiano45]

1 monkey accessed youtube.

[super1range]

wow i didnt understand log in class at all, finally a video that shows everything thank you again so much! also what is the inverse property?

[mikej941126]

"so what the heck is a logarithm?..." I was going to ask that!

[Peasant001]

I've been lost in my logs unit for over a week now... until i saw this video of course !

[frienducankeep]

a leftie.. great!!

[bigscoach]

1 person didnt understand logs.

[JNCOKING20]

dude sweet better understanding like i knew the answers to some problems but i just needed to know the work to get there lol

[idaho777]

at 7:10, since there is log(x) + log(y), can you cancel out the logs if the equation is equal to another log(number)? so log(x) + log(y) = log(z), then x+y=z?

[bigscoach]

@idaho777 Yes, you can.

[KeybladeAli]

such a helpful video

ur writing was really neat!

[collins984]

you great!!!thanks a lot!

[Bartney1994]

Thank you

[ChannelTofu]

what's the purpose of 'log' actually? what's the value of log? I fairly get equations and what you're doing, but why is log involved? I just dont get it.... =|

[SCSRoblox]

@ChannelTofu

"log" isn't a value. "log" just means that the expression is a logarithm.

[darkhunter454]

so bascially, i looked at my math exam overview, and it said KNOW LOGARITHMS...and i said to myself "omg i dont know anything about logs" i then soon realized that i could come to you once again for help!! :) thank you so much! you cover everything in my 12u math course.

[patrickJMT]

@darkhunter454 i am always here! : )

[lisbetse286]

I LOVE U!!!!!!!

You are the best!!!!

[antoinetteisfly]

I don't understand why they can't replace Bonnie (my teacher, it pisses her off when I call her that) with you. You...are...AWESOME. thank yooouuu.

[patrickJMT]

@antoinetteisfly be nice to your teacher! : )

[yondy12]

my bro told me log is easy im trying to do it now and i feel like a stupid retard...

[patrickJMT]

@yondy12 i think most people find them tricky at first, so hang in there!

[njfife14]

This is good stuff, I am reviewing logs for my calc class. It is hard to manipulate some of the larger calc problems if you can't remember the rules and basics of Log's, so thanks for the help. your videos have been the most clear of any I have found in general. The often exceed my class time in terms of time spent to learning gained.

[oreion69]

Thank you! Your videos are very helpful because you do such a great job at demonstrating mathematical principles!

[gustaya]

great video, but somehow i can not turn the volume up....?

[krisnalla64]

holy shit, you are god. three weeks of review ain't got nothing on this

[HLGREDUX]

I LOVE YOU
