Hey, I just need you guys to help verify that I got the correct answers on some of the even integration problems in my book. If one of them is incorrect, I'll post my work and hopefully can find out where I went wrong. Thanks!
1. \int xcos(x^{2})dx = \frac{1}{2} sin(x^{2}) +C
2. \int x^{2}cos(x)dx = x^{2}sinx + 2xcosx - 2sinx + C
3. \int x^{2}e^{-x}dx = -e^{-x}(x^{2} +2x + 2) + C
4. \int e^{x}sinxdx = \frac{1}{2}(-e^{x}cosx + e^{x}sinx) + C
