1. Homework Statement
Find the interval of convergence of f'(x)
f(x) Sum from n=1 to infinity [(x-5)^n*(-1)^n]/[n5^n]
2. Homework Equations
3. The Attempt at a Solution
My problem is I am unsure how to take the derivative with the n's and x's should I treat n as a constant?
After that, I think I can get the interval of convergence.
