1. The problem statement, all variables and given/known data I am working on an integration by parts problem, and in order to work it I need to figure out the anti-derivative of ex/2. We've covered basic integration concepts, the definite/indefinite integral, u-sub, and integration by parts. Now, examining the derivative, I expect the anti-derivative to be 2ex/2, but I can't show my work on how I get here. I tried u-sub and I just get the same function.
