Nettet16. mar. 2015 · my problem consist of several trigonometric functions in a fraction and that whole thing should get integrated: ∫ ( tg x + cotg x) 2 sin 2 x − cos 2 x d x. The only thing I can do is to rewrite it to a form ∫ tg 2 x + 2 + cotg 2 x ( sin x + cos x) ( sin x − cos x) d x which is leading me to partial fraction and/or substitution, but it ... NettetTo tackle these trigonometric integrals, we usually decide how to proceed based on what the powers of the trig functions in the integrand have. Namely, we have the following three cases: For a general integral ˆ sinm(x)cosn(x)dx, Case 1: If m is odd we can write m = 2k +1 and use the identity sin2(x) = 1− cos2(x) to obtain: ˆ sinm(x)cosn(x ...
