Hello, Preston019!

I'm having a lot of difficulty figuring out: .

My instructor said something about "Looping the Integral" if that helps at all.

The instructor also gave us an example of: .

But I'm not sure how to go about the first one I gave.

Did you understand your instructor's example?

If not, no wonder you can't solve this one.

Maybe I'd better baby-step through it . . .

We have: .

Integrate by parts: .

We have: .

Therefore: .

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

We have: .

Integrate by parts: .

We have: .

Since we know the value of , we can finish the problem . . .
