A friend of of mine has a problem with an integral and since it's for his thesis, it's pretty important.
That's why I ask it here cause I don't know where to ask it elsewhere, so if it's wrong posted, completely my bad.
With other words, I want to integrate the wole thing to the variable o, who appears in the variables l and R.
Somehow, when I put this in Maple, it won't solve it. Probably it's just a stupid fault or i just forget something, but i don't find it. Does anyone knows how to solve it?
Already a lot of thanks!
