Hi, I have a couple of things I am stuck on.

1.

Use the dominated convergence theorem to find

where

I deduced that since the sequence converges to 0 pointwise and we have dominating function such that .

All I need to do now to show that the dominating function is integrable so that the sequence of the integrand converges to 0.

But how do you show this?

2. How do you show that a sequence that converges to in then

Cheers
