let . Thus,
Now, the integral becomes
Now integration by parts will be a piece of cake from here.
Why don't you take it from here and find and .
PS: In the future, if you have new questions, please ask them in a new thread.
To determine what should be, you can use the anagram LIPET. Go down the list (in this particular order) and see what you have in the integral [i.e. if you don't have logs, do you have inverse trig? etc]:
Logarithms (Natural) --------------Highest priority
Inverse Trigonometric Functions
Trigonometric Functions -----------Lowest Priority
