Transcript

in this video we're going to find the derivative of this function so before we do it we're probably going to rewrite this using some properties of logs because if we just try to take the derivative right away we're gonna end up having to take the derivative of this inside piece using the chain rule and that's no good so let's go ahead and start by ...
