I'm trying to solve an infinite series problem, but I'm stuck. It's not
a deep mathematical mystery. It's just a problem in a calculus book I'm
reviewing. It has been more than 20 years since my last "homework"
problem, but I try to review this stuff from time to time on my own so
I don't lose it as most of my classmates from those days have long
since done.

I praise you for struggling valiantly. I will give you a hint. Use formal power series.
