Homework Statement




Let F(x) = [tex]\int^{x}_{0}xe^{t^{2}}dt[/tex] for [tex]x\in[0,1][/tex]. Find F''(x) for x in (0,1). Caution: [tex]F'(x)\neq xe^{x^{2}}[/tex]

Homework Equations





The Attempt at a Solution


I just need a hint. I know what F"(x) is already (solution was given), but I'd like to find F'(x)

Thank you

Your derivatives are with respect to x, right? Look up the Leibniz integral rule.

Thanks for your reply. This is from an Analysis course so we didn't cover Leibniz's integral rule. Can you offer any additional hints?

Ok, factor x out. It's not a function of t. Now use the product rule and the fundamental theorem of calculus.

Thank you very much for your prompt reply. I never thought about factoring out the x. So I guess that was standard procedure. Any variables that is not a function of t may be factored out.

I appreciate your help.
