# Taylor Series

## Homework Statement

Find the Taylor Series for f(x) = 1/(1-6) centered at c=6

Ʃ Fn(a)(x-a)/n!
n=0

## The Attempt at a Solution

I believe that the nth derivative of 1/(1-6x) is

(-6)n-1n!/(1-6x)n+1

So i figured that the taylor series at c=6 would be

(-6)n-1(x-6)n/(1-6x)n+1

What am I doing wrong here?

Did you mean: $$f(x) = \frac{1}{1-6x}$$ ... from below, it appears so.

Ʃ Fn(a)(x-a)/n!
n=0

## The Attempt at a Solution

I believe that the nth derivative of 1/(1-6x) is

(-6)n-1n!/(1-6x)n+1
What leads you to believe that?
So i figured that the taylor series at c=6 would be

(-6)n-1(x-6)n/(1-6x)n+1

Start from the definition of the Taylor series.
Try writing out the 1st 3-4 terms and see if you spot a pattern.
