i don't get it. something about nice guys/friend zone?

She'll get "put out" by the bad boy.

Continued from last thread.
Where does the arcsin come from when you integrate sqrt(25=x^2)?
Is there an easy way to explain how to do this?
-t. calc 2 brainlet.

Short answer: trig
Long answer: read a trig book
Medium answer: Just try to integrate eith that technique. The trigonometric functions have a nice property that allows you to turn a complex integral (complex=not possible to evaluate) into a simple integral (possible to evaluate). What those properties are will be apparent from the moment you try do trig sub. It is literally the entire point of trig sub.

This is going to be a fun semester.

if you know basic trig functions like sin^2(x)+cos^2(x)=1, half/double angle formula, tan^2(x)+1=sec^2(x) you will be okay for trig substitution.

Well, trig sub is just the fancy name given to the general and completely developed technique. If you know trig you can figure out the simple special cases to integrate that. You can easily "discover" trig sub because it is simply sin^2 + cos^2 = 1

Is there a place for calc review problems? Like calc1-4?
