Hi to you,

Q: Find the Maclaurin series of .

Also find the associated radius of convergence.

A: So far I have found this:for the first part

.

so it follows that:

.

and so:

n going from 0 to infinity.

That is:

I am right for the first part?

Second part:

I did the ratio test and I got that the limit is smaller then 1.

Therefore the sum is absolutely convergent...???

Thanks in advance,
