I'm accumulating notes with every problem regardless, but are there any calculus-specific trig identities you'd recommend knowing? Please help me bulk up the cheat sheet, I have an exam on Sunday, haha. Pythag orean Identities sin x + cos x 1 tan x + 1 secx 1 + cot x csc x. Obviously some of this is meant to be derived from the basic identities, but I feel like I'm missing something every time. Prove the following trig identities using only cos2(x) + sin2(x) 1 and sine and. Use these to find (a) any trig function, given two known functions or (b) a 15pi function that isnt on the 16-point unit circle. Welcome to our dynamic online platform, where knowledge meets entertainment in a seamless blend of news, games, and fashion. the antiderivative of secx = ln|secx+tanx|+C or sinxsiny=1/2(cos(x-y)-cos(x+y)). 16 years ago? Anyway, I've written out a cheat sheet with basic trig identities and indefinite integrals from Stewart's textbook, but I'm currently in the section where we're just doing integrals of exponential trig functions and it seems like every problem involves a crucial trig identity I don't know (i.e. I'm doing okay, but I tend to get tripped up on integration involving trig functions because everything I learned about trig was in precalc in high school, so. Any advice on this? I'm a returning student taking calc 2 now, about 12 years after taking calc 1.
