I'm trying to evaluate the integral:
The integral seems to be challenging (computer algebra systems will have a long time dealing this integral). But, the book where I got this integral from came with a hint:
What is the value of: in the context of the problem?
I'm stuck. How should I continue? Thanks for any advice!
Here's my argument. So if we call the expression under the square root I, and we get I again when we simplify the hint, I can set sqrt(I) = I and solve. I end up with I to be 0 or 1. I'm not sure this logic makes sense, but it's an effort. Does this seem legit?
You can't set the sqrt(I)=I
that's like saying sqrt4=4
Topsquark has done most of the work for you.
You just have to make sense of it.
He has left you at a spot where you can integrate directly. just change the square roots to powers of a half.
