Taylor Series of f(x) = 1/(1-6x) at c=6

Click For Summary
SUMMARY

The discussion focuses on finding the Taylor Series for the function f(x) = 1/(1-6x) centered at c=6. The user initially attempts to derive the nth derivative and construct the series but misidentifies the function as f(x) = 1/(1-6). The correct nth derivative is expressed as (-6)^(n-1)n!/(1-6x)^(n+1), leading to the Taylor series representation of (-6)^(n-1)(x-6)^(n)/(1-6x)^(n+1). The discussion emphasizes the importance of starting from the definition of the Taylor series and suggests writing out the first few terms to identify patterns.

PREREQUISITES
  • Understanding of Taylor Series expansion
  • Knowledge of derivatives and their computation

Homework Statement



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

Homework Equations




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.

What leads you to believe that?

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