Sorry, but I can't quite make out the integrand. Is it supposed to be $\displaystyle \int _0^1 \int _{2y^{3/2}}^{2y} \frac{y^2}{x^2} e^{(x  2)^2 /2} ~ dx~dy$ The x integration is supposed to come first but I don't think it has an exact form. So what I would do is to switch the integration to dy dx. I'll leave the process of changing the integration limits to you. I have included the graph that will help. Can you finish from here? Dan
