(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

integrate cos ^3(πx-1)

2. Relevant equations

1-sin^2(πx-1) = cos ^2 (πx-1)

3. The attempt at a solution

(1-sin^2(πx-1))cos(πx-1)

Let u = πx-1

1/ πdu = dx

1-sin^2(u )cos (u)

1/ π(X-1/3sin^3(u)

Basically I'm Confused on how to get past the trig identity part.
