use u = sec x to evaluate
Offline
So use u = secx and evaluate. Whats the problem?
Now integrate!

Sure, it's easy when you know how to do it.
I didn't know to change the tan^2 to it's sec equivalent.
Thanks.

sin²x + cos²x = 1
Divide through by cos²x
tan²x + 1 = sec²x
Subtract 1 from both sides.
tan²x = sec²x - 1
There are 10 types of people in the world, those who understand binary, those who don't, and those who can use induction.

Then you should have stated what it was you found difficult about the problem. That way we know that youve tried the problem yourself and arent just being lazy. The way you posted your problem here seems to suggest otherwise. (There are people here who would just post their problem without even trying, expecting us to do all the work for them then they would come back later and copy our solutions as answers to their homework. We dont want to encourage such bad habits here.)
