Power Series

Postby bs42 » Thu Mar 29, 2012 9:42 pm

I didn't really know where to ask this, but we're going over this is my class and I have no clue how to find the power series of:

3 / (1-x^3)

Do I take the derivative twice?

I got 3[2 + 6x + 12x^2 + 20x^3 + ... + n(n-1)x^(n-1) + ...]

I'm pretty much clueless here.

I believe. I'm rusty, but I think that works.
