Indeed. You can try , so , the last integral being (almost) immediate
since it is of the form
First substitute and then use once an integration by parts.
You could try a substitution first...
Your integral becomes:
That is easily integrable by parts. , , ,
And there you go.
Where did the come from? What happened to the original ?
Nevermind, I see with the substitution that dw=2x times the w=x^2 does indeed solve my problem. Thanks guys.
