The following table lists a few values of g, h, and g prime. Alright, so they want us to evaluate h prime of three. They don't even give us h prime of three, how do we figure it out? They gave us g prime and h and g. How do we figure this out? Well here we're going to actually derive something based on the chain rule. And this isn't the type of problem that you'll see a lot of, but it is interesting. So we're going to work through it, and there's a chance that you might see it in your calculus class.
