## Homework Statement

The function f(x) = 8x*arctan(6x) is represented as a power series f(x) = sum from n=0 to infinity of Cn * x^n

Find the first few coefficients in the power series

## Homework Equations

## The Attempt at a Solution

I deduced that

8xarctan(6x) = sum from n=0 to infinity of 8(-1)^n * 6^(2n+1) * x^(2n+2) / (2n+1)

but I'm not sure how to go about to get it into the from Cn*x^n

Any help will be great. Thanks
