I don’t know how to start with 1b and 1c, need some help here.
Look, I am not looking for answers. I just need some guidance.
Thank you

Hey wesleybrown.

Hint: Consider that for Riemann integrals that the integral of [a,b] = Integral of (a,b] in terms of the domain of integration.

3. ## Re: Improper integral

So embarassing, I am stuck again. This time is on 2c. I ve seen people doing it by complex plane, but I don’t think my instructor want to see that. By double integral, I have gone as far as pluging in infinity to the antiderivative I obtained, and it turns out to be a sin(infinity). Need help again...
