Math Help - finding area under a weird curve and lines

1. finding area under a weird curve and lines

hey all, I need a help to find the exact area under the graph of
f(x) = x*e^(x^2) between x = 1 and x = 3.

thanks a lot,
Tuugii

This is just to compute

$\int_1^3 {xe^{x^2 } \,dx} ,$ and this is a trivial integral to solve.

3. got it! thanks
