n th derivativethe problem is to prove that ∫(1 to 1) u^(n1)(x) u^(n+1)(x)dx = (1)^n ∫(1 to 1)u(x)u^(2n)(x)dx #2 20130816 02:29:11
Re: n th derivativeHi; That is the LHS of your question. Refresh my memory, which polynomials are u(x)? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130822 02:43:01
