    I added some more detail. Let me know if you need any clarifications, but the solution is pretty much what I have written.

    Can you explain why the integral converges if the lim is 0?

    I am not saying that he integral converges if the lim is 0. If the limit is not zero then the integral is divergent. This is a well known fact about improper integrals which can be easily found in any calculus textbook.
