Wow! Very Clear and very Helpful. =]

[Saronaist]

Thank you so much. U r the best.

[MASTERmw100]

no this is gay and boring

[AtactHD]

Im 15 and dis shit is interesting as hell

[ADTRrocks14]

I've learned more from you now, than from my Pre-Cal teacher all year! Thank you Professor!!

[coresnake0]

This guy is like the second coming of Newton lol

[gmandog6]

i love you

Good video

[alonescool]

anybody high?

[Heathh49008]

Excellent! Concise, well explained, and just what I was looking for to review.

Thank you!

Professor i just want you to know that u are really helpful, i am a freshman in college and you taught me more in 1 hour 12 min and 41 sec what my High school teachers, college professor and TA couldn't!!!! (That's an overstatement) I just get carried away with so much knowledge. Thats all i gotta say about that!

[lindathenavigator]

Thank you so much! I found this lecture really helpful.

I have a question, though. At around 45:30, why do you have to switch the axis, or the x and y values when drawing inverse trigonometric functions? I mean, when the professor was drawing the inverse function of y=x cubed, he just drew it directly on the original graph. I'm confused... I'm a high school student in Korea, and we don't learn inverse trig functions here until college.

I would really appreciate your answers.

[tordack]

@lindathenavigator The drew the inverse function on the same graph to show that it was a reflection of the original function. Think about what a function is as opposed to the inverse function, though: a function (x, f(x)) is simply an inverse function (f(x), x) but with the domains (x and y values) switched. To draw that on the same graph you would have to switch the domains (x and y values) and put x's where there are y's etc. I hope that helped - good luck!

[lindathenavigator]

@tordack thanks, that helped!! By the way, I got 5 in both AP Calculus BC and AB for subscore this year. Yay~

[tordack]

@lindathenavigator Good job:) It takes a lot of work!

good shit

[EngineerHughes]

This is a very long Lecture,

thorough though what, what!

[intelligenceisacurse]

At around 52 minutes on the part that says simplify tan ( arcsinx) I have a question.

Would this simplification actually be correct? How do you know if the triangle is actually a right triangle?

[richewhite]

@intelligenceisacurse , based off of the unit circle, where hyp=1, you can make any angle measured via a right triangle. refer to the beginning of the video
