3. if F(x)= find F'(16)

Hi, any help would be wonderful. I really need the explanation more than the answer, though.

1. Subsitute remember that

2. Subsitute

3. Define so that (1)

Now differentiate in (1) using the chain rule and remember that - April 17th 2008, 10:59 AMTKHunny
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 "d"?__t__

Let's see what you get. - April 18th 2008, 12:21 PMMoo
Hello,

For the first one, a substitution u=cos(x) is quite a valid way to solve it too ^^ - April 18th 2008, 01:20 PMcolby2152
