In the previous posts we covered substitution, but standard substitution is not always enough. 2015-04-22 cos((n − 1)x − x) = cos((n − 1)x) cos x + sin((n − 1)x) sin x. It follows by induction that cos(nx) is a polynomial of cos x, the so-called Chebyshev polynomial of the first kind, see Chebyshev polynomials#Trigonometric definition. Similarly, sin(nx) can be computed from sin((n − 1)x), sin((n − 2)x), and cos… 2015-11-09 We can't just integrate cos^2(x) as it is, so we want to change it into another form, which we can easily do using trig identities.

Hade det stått cos^2x hade jag varit.

To integrate sin^2x cos^2x, also written as ∫cos 2 x sin 2 x dx, sin squared x cos squared x, sin^2(x) cos^2(x), and (sin x)^2 (cos x)^2, we start by using standard trig identities to to change the form. We start by using the Pythagorean trig identity and rearrange it for cos squared x to make expression [1].
