Hello, I was wondering if someone could explain this problem:
Expand f(x)=x^3/(1+x^3) in powers of x for abs(x)<1.
I think it's a maclaurin expansion, but I've evaluated up to the 9th derivative at f(0), and I come up with 2 terms. How long do I have to expand it? or am I just doing it wrong.
Thanks.
