Best ResponseYou've already chosen the best response.0No, dv/dx = e^x. You can't set v without first setting v', when doing integration by parts.

Best ResponseYou've already chosen the best response.0You're going to end up doing that type of integration 2 or 3 times if I'm not mistaken; unless you're familiar with tabular integration.

Best ResponseYou've already chosen the best response.0Yes, once you get that second ∫v du you're going to get another ugly one, so do integration parts on that one too.
