Homework Help: MATH

Posted by A. on Tuesday, December 4, 2012 at 2:27pm.

Expand f(x)=ln (1+x/1-x) in a Taylor Series about x=0. You must express your answer using summation notation.

---This is what I tried to do---
So I was thinking of taking the derivative of ln(1+x/1-x) and get 2/x^2-1

And then use the identity 1/1-x= sum x^k

So then it will be Sum (-2^k) (x^2k)
