I need to solve this integral, but I get stuck in some point and I can't go on. I explain what I have been trying:
Changing the variable as
So "u" would be:
Desarrollando esta expresión,llegamos a que:
Por lo que
The derivative of u with respect to:
Replacing these terms in the original integral we have:
When I get to this point, I don't know how to go on. The result of the integral would be like this:
I tried operating in other way, like this:
Doing the change of variable we have this:
But again, I don't know how to continue.
Could you tell me what could I do to go on with the integral?
