int_0^pi/2 cos^2x dx/cos^2x+4 sin^2x

This is an excellent question, and it comes down to logic. Let's look at a “proof” of cos2 x sin2 x = 2cos2 x 1. Add 1 to both sides:. sin5 x dx = ∫ sin x sin4 x dx = ∫ sin x(sin2 x)2 dx = ∫ sin x(1 - cos2 x)2 dx. 1 dx = x and. ∫ -3 cos 2x dx = -32 sin 2x are easy.

Calculus Introduction to Integration Definite and indefinite integrals. 1 Answer sin 2 (x) + cos 2 (x) = 1. tan 2 (x) + 1 = sec 2 (x). cot 2 (x) + 1 = csc 2 (x). sin(x y) = sin x cos y cos x sin y. cos(x y) = cos x cosy sin x sin y cos 2 θ = 1 + cos(2θ) 2 sin2 θ = 1 − cos(2θ) . 2 Because we have to do a lot of writing before we actually integrate anything, we’ll start with some “side work” to convert the integrand into something we know how to integrate.
