I need to find the interval and radius of convergence of the power series.
I forgot which steps I should take to solve this, Any & all help is appreciated!
∞
∑ ((-1^n)*(x^n)) / ((n+1)(n+2))
n=1
Just for the record, this is not homework, it is part of the review for my final exam (which is in 2 hours!) D:
It can be found at this address, in case you doubt me.
My web Page
If you know how to solve this, I have a question:
How do you know which values to test out for convergence (in order to find the interval)?
Is this just a random test, or are there steps to take to figure out possible values in the interval?
Thanks in advance!
