so
for
divide the into each term in the numerator, you get
each of those integrals you should be able to do. Hint: think "what functions would I take the derivative of to get these?"
As for the derivative problems: please clarify what F(x) is. is it or . more than likely it's the first. in either case, you are going to have to use the chain rule and the product rule. do you remember these? what have you tried?
for you will also need the chain rule.
recall that the chain rule says:
here, and
now try it.
by the way, the places where you put *, you shouldn't put *. students make mistakes with this all the time, it is WRONG to think of something like sin(x) as sin times x. sin by itself makes no sense, it is not a product!
