Would it hurt to memorize the trig ident in the paint doc?
I am thinking if I do it will save me some time in the long run with integrating.

Also, I know I've asked this question before but I can't seem to find my old post... can some one send me a link of important integrals to know, (not the common ones you can find in a book.)

IMO, the only identities worth memorizing are the two for sin²(θ) and cos²(θ). The others can be derived from these two, if needed.
