Integrate e^-(x^2)
I think the easiest way to integrate x e^(-x^2) is by substitution. First left u = -x^2 then du = -2x dx then you can rearrange du=-2x dx to become -(1/2)du=dx then the integration of xe^(-x^2)dx becomes e^u(-1/2)du which you can take out the constant of (-1/2) results in [(-1/2)e^x^2] + C...- JDUBBS2344
