    Question on Integral problem

    Would this be correct? I'm not sure if the negative in front of the integral should effect the + C.
    \int cot^4xcsc^2x  u=cotx   -du=csc^2xdx
    -\int U^4du
    -[\frac{1}{5}u^5 + C]
    -\frac{1}{5}cot^5x - C

    If you calculate x - c = y instead of x + c = y, either way, you're going to get y. So technically, you could say -1/5cot^5x - \frac {4\sqrt c}{5} and it wouldn't make a difference when applied.
