3. if F(x)= find F'(16) Hi, any help would be wonderful. I
really need the explanation more than the answer, though. What
are your thoughts? 1. A substitution looks easy enough. u = ???
2. Begging for Integration by Parts if you want to learn
something, but a simple substitution of everything under the
radical might be a lot easier. 3. A derivative of an integral?
Don't forget the Chain Rule. This one likely is ill-formed, Do
you mean "dt"? Let's see what you get.
