Integral of Cos^2 - The Math Forum @ Drexel University
Date: 6/13/96 at 13:58:39 From: Doctor Charles Subject: Re: Anti-derivative for Calculus Well: d/dx[(-(cos x)^3)/(3 sin x)] = (9(sin(x)cos(x))^2 -3 (cos(x))^4))/(9(sin(x)^2) = (cos(x))^2 * (1 - (1/3) (cot(x))^2) so I am afraid that your solution doesn't ....
