[tex] f(x) = \frac{1}{(1-2x)^3}[/tex]
Homework Equations
R = 1/L
The Attempt at a Solution
I have the full solution set for this problem but i can't figure out the process they are using to obtain the answer. I'm pretty unclear on specifically what the answer is supposed to be. I see that i am supposed to write the series in summation notation, but i don't know all of the steps.
For some reason they begin taking derivatives of the series given in the question and i have no idea why. All i really need help with is how to approach the problem. A little insight on what I'm supposed to be doing here would be great.
Thanks,
