Malfunction

Yeah, but how exactly do you subtract from the integrands? Like, say, a function is rotated about the line x=5. What exactly should I do to translate the function?

Also, a rather off-topic question: sometimes, you have to find critical points of a very complex function. How exactly would I go about doing that? Even a calculator fails to give me the critical points of functions like x+4e^(sin4x). I just get a blank list. Is there a specific program or trick to do these?
