Fuck Mathematics.

[CrispinDan]

this is trippy

[DCJAMERICAN28]

This stuff gives me a headache...

[HiDeguild]

I didn't like college algebra, not one bit. But, I passed it. Thank you, UMKC.

[raylech19861]

Awesome!!! I have a computer science degree and a heavy mathematics background...and the WAY the material is introduced and explained is the BEST I've ever seen!!!!

[tska84]

i refuse to stop the tape!!

[tska84]

@ARQ911 have you watched lecture 28? if not you should. he starts of a little more basic at explaining things. it might help you understand what he's talking about better.

[bangalorebully]

HAS ANYONE GONE THROUGH ALL 40 LECTURES OF THIS SERIES???PLEASE DO MESSAGE ME...I AM SET TO DO IT AND WOULD LOVE TO GET YOUR FEEDBACK...SORRY FOR THE CAPS!!!

[danagamer]

fyi, the section on Logarithmic functions begins at 24:00

[grecojones]

Thanks much, UKMC!

god i hate logs

[normandyangel]

im a 10th grader and im in algebra 2 and were doing this!!

[texasbeu2y]

man,i go to school in houston and 1314 or college algebra is killing me. Is there any substitue like in high school!  Can i take math and money or something like that?

[ZAN871]

is this a required course in college?

[tedirelan]

@ZAN871 Yes. In Every College.

[wiredboy27]

delaware and wildberger are the best in the entire world 

[TheLittleTrickster]

On 27:57, he says y=log (sub a) x but, why does he says when he substituted x with a^y that log (sub a) a^x = x? Shouldn't it be equals to 'y'?

[dralpeshkorat]

@TheLittleTrickster - It looks like y=log(sub a)X, inverse to x=a^y, are the functions he uses to initially explain this excerpt. But, he then creates two different inverse functions: a^x=x, inverse to log(sub a)X= x, to explain in further detail. I'm sure he would have noticed if it was a mistake once he started talking about the 'x's'.

[Whiscash90210]

Don't let him fool you. He's very arrogent and rude in the classroom. I had him once. He's an awesome teacher but he sucks as a person.

[Meastemia]

Dude!!! This video is epic!

Saved my butt for my upcoming exam!!! lol

[Taxminia0311]

blahblahblah

[tooskool4cool]

@Taxminia0311

i liked it

[13zombielover]

great teacher, covers everything in detail!

[trobe23z]

This guy is a great teacher very comprehensive

[rngoodwin630]

reallyyy helpful video THANK YOU!! :D

[mountain3goat]

Thank you sooooooooooooo much!!!!!!

[nimonimo54]

hi

is log1/3 (-x) = - log 1/3 (x)

so why we have reflected the graph around the y- axis not around the x- axis as we did in the previous example ?????

[AVerbene]

wow, i have this stupid bitch streight out of collage math teacher. she did such a shitty job teaching us this stuff. this guy does a really good job of explaining

[TheUSAFPatriot]

I relly gud at maths but not for english and the languages i frm southern africa of the south

[peacetake123]

Wow; Making simple concepts so difficult.

[juanbarros88]

the reason I failed my College Algebra FInal... I hate my teacher and his challenging questions, hahaha

[hachem53]

x is used in the exponential function as the exponent, the result f(x) being a number, which can be also called x as the variable of the log function. this is in itself a very simple idea, but using the same variable in the same sentence and the same graph is didactically unsound. it only makes sense for people who have had a lot of experience with exponential and log notation. for the rest of us, your primary audience i hope, it is utterly confusing.

still, i enjoy your lectures very much.

[TheyFeedingULies]

Execellent video! The explanations were extensively concise (oxymoron). Just watching ur videos saves me the cost of a tutor which is $20/hr! I owe you large.

[P3RSIANpinoy]

2 thumbs up! Great video! Im definitely coming back!

[jesusclau1]

I love your vids. I can't stop watching them!! Thank you!!!

[P3RSIANpinoy]

geek LOL!

Just Kidding

[Johnjpcoc]

Sorry, but the way his teaching is really sucks!!!

[marianiiina]

i like it :P

[biglebowski565]

I don't think it sucks, I think it's pretty good. Better than most teachers.

[P3RSIANpinoy]

Just judging by this one lecture I give him a 9 out of 10

[emblemOFbeing]

richard delaware puts the fun in function

[tryme112333]

Hey I'm from India and i found this extremely helpful but i was wondering if you have anything on advanced trigonometric identities..

[Omega231984]

I don't think there are any right now

[Aftanyalghafel]

very clear. Thanks a lot!
