For the function f(x) = sinx*cosx the integral of it by u-substitution could be -(cosx)^2/2 or (sinx)^2/2, which one is right for an assignment or would I need to state both? Also for a person taking first year physics, what kinds of integration will I need to know past, integration by parts, and integration by substitution?(adsbygoogle = window.adsbygoogle || []).push({});
