I do all the work, and come up with some ridiculous fraction:
Take limit as n-> inf and I get zero?
I used maple as well to check and it gets:
take limit and it becomes infinite.
Which is right?
I did not show all my steps. i used the ratio test on the original problem and as you guys know, replace all n with n+1, times by reciprocal of fraction etc, You then get what i have above. I used a calculator for mine, and then tried to duplicate it with maple but get two different answers. What I need to do is find the radius of convergence.
