Finding Taylor Series for (x-1)/(1+x) at x=1

Click For Summary
SUMMARY

The discussion focuses on finding the Taylor series for the function \(\frac{x-1}{1+x}\) at the point \(x=1\). Participants suggest transforming the function into a more manageable form, such as \(\frac{1}{1+a}\) or \(\frac{1}{1-a}\), to facilitate the series expansion. Additionally, the use of the Taylor series formula \(\sum\frac{f^n(1)(x-1)^n}{n!}\) is proposed, emphasizing the need to compute the derivatives of the function at \(x=1\). The conversation highlights the importance of proper function manipulation and derivative calculation in obtaining the series.

PREREQUISITES
  • Understanding of Taylor series expansion
  • Knowledge of function manipulation techniques
  • Familiarity with derivatives and their computation
  • Basic algebraic skills for simplifying rational functions
NEXT STEPS
  • Study the derivation of Taylor series for rational functions
  • Learn about the manipulation of functions into standard forms like \(\frac{1}{1-a}\)
  • Practice calculating derivatives of functions at specific points
  • Explore examples of Taylor series expansions around different points
USEFUL FOR

Students in calculus, particularly those learning about Taylor series, mathematicians, and educators looking to enhance their understanding of series expansions and function manipulation techniques.

find taylor series for \frac{x-1}{1+x} at x=1

Homework Equations


The Attempt at a Solution



how to change this form

\frac{x-1}{1+x}

to something like this
\frac{1}{1+a} or \frac{1}{1-a}

help me please T_T

or should i do like this

\sum\frac{f^n(1)(x-1)^n}{n!}

and find fn(x) form?
