1. The problem statement, all variables and given known data Compute: ∫x2(Hn(x))2e-x2dx The boundaries of the integral are -∞ to +∞ 2. Relevant equations By Rodrigues' formula: Hn(x) = (-1)nex2dn/dxn(e-x2) 3. The attempt at a solution I proceed to plug in my expression for H into the integral, however, I'm insure as to what happens to the dependent derivative/integral when the derivative is squared. I believe the solution to this problem is straight "plug and chug." I got stuck pretty early and don't want to proceed until i know what to do with the derivative. Thanks in advance for your help!
