Question: By considering \(S_{n}=1+x+x^{2}+\cdots+x^{n}\), or otherwise, show that for \(|x|<1\)

\[\frac{1}{1-x}=1+x+x^{2}+x^{3}+x^{4}+x^{5}+\cdots\]

Use this result to find the Taylor series of the functions below and indicate the values of \(x\) for which the corresponding series converges:

\[\text { (a) } \frac{1}{2-x}, \quad \text { (b) } \frac{x}{1+x-2 x^{2}}, \quad \text { (c) } \log \left(\frac{1+x}{1-x}\right) \text { . }\]
