im trying to integrate 15xe^(-x^2) on [0,1] and I cant figure out what to do. I think you are supposed to integrate by parts, but i cant even figure out where to begin, let alone assing a u or dv.

no. substitution, $\displaystyle u = -x^2$
or get around this by noting that you have
$\displaystyle - \frac {15}2 \cdot -2xe^{-x^2}$
which is of the form $\displaystyle - \frac {15}2 u'e^u$
