    Going into a test tomorrow about Derivatives of Exp/Log Functions!

    Anyone have any last minute tips for me? I've done a lot of studying and I'm hoping I know everything...

    I do have a question.

    It's a very urgent homework help question.

    I need to poll the people here for my calculus class. The question?

    WHO HERE LOVES CALCULUS?!

    log_a(u(x))=\frac{\ln(u(x))}{\ln(a)}

    Therefore \frac{D[\log_a(u(x))]}{dx}=\frac{D[\frac{\ln(u(x))}{\ln(a)}]}{dx}=\frac{1}{\ln(a)}\frac{D[\ln(u(x))]}{dx} =\frac{u'(x)}{\ln(a)u(x)}
