Homework Statement

To find the general series expansion (1-x)^-1 for the first 4 terms
Do i just use the taylor series ?

Homework Equations

f(x) = f(x) + f '(x)/1! x + f ''(x)/2! x^2 + f '''(x)/3! x^3

The Attempt at a Solution

= 1 + x + x^2 + x^3 + x^4 etc.

Looks good, except the taylor series of any function f around 0 is

$$\sum{\frac{f^{(n)}(0)x^n}{n!}}$$
