Question

Can anyone explain in details the trigonometric integration function of cos 3 x sin x dx?

Answer 1

Answer:

Integrals

sin x dx = -cos x + C Proof csc x dx = - ln|csc x + cot x| + C Proof

cos x dx = sin x + C Proof sec x dx = ln|sec x + tan x| + C Proof

tan x dx = -ln|cos x| + C Proof cot x dx = ln|sin x| + C Proof
