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

∫cos(x)sin^6(x)*dx

2. Relevant equations

3. The attempt at a solution

u=sin(x) then du should be -cos(x) according to the integral tables?

-∫u^6*du = -u^7/7

-sin^7(x)/7+c yet my book and calculator tell me the answer is positive. How??????
