Anyone knows what function correspond to this series expansion?
[tex]
\begin{align}
f(x)=1+x+x^2+x^3+...
\end{align}

\begin{align}
f(x)=1+x+x^2+x^3+...
\end{align}

A series expansion is a mathematical technique used to represent a function as a sum of infinitely many terms. It is often used to approximate a function that is difficult to evaluate directly.
A series expansion allows us to approximate a function with a simpler, more manageable expression. This can be useful in solving complex problems or analyzing the behavior of a function.
A series expansion is typically calculated using a mathematical formula, such as the Taylor or Maclaurin series. These formulas involve taking derivatives of the function at a specific point and evaluating the function at that point and its derivatives.
The purpose of finding the function that corresponds to a series expansion is to obtain a more accurate representation of the original function. This can be useful in analyzing the behavior of the function and making predictions about its values at different points.
The accuracy of a series expansion can be determined by comparing its values to the values of the original function at different points. Generally, the more terms included in the series expansion, the more accurate it will be.
