Good video as always; thank you. Erratum: at 5:05, "much easier than using either the quotient or the power rule" should be "much easier than using either the quotient or the *product* rule."

Watched this video because I was looking for an explanation of how to deal with a function raised to the power of another function, for example lnx^(cosx). This video maybe should have mentioned the trick of using the power rule property of logarithms to manipulate. Does Khan Academy have a video on that subject?
