...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:
n going from 0 to infinity. n = 1 to infinity
I am right for the first part?
I did the ratio test and I got that the limit is smaller then 1. yes, 0 is < 1
Therefore the sum is absolutely convergent...??? correct
