Series expansions are mathematical representations of functions as infinite sums of terms, where each term is calculated from the function's derivatives at a specific point. These expansions allow functions to be approximated or expressed in a more convenient form for analysis, computation, or theoretical work. There are several types of series expansions, but the most common ones include: 1. **Taylor Series**: This representation expands a function \( f(x) \) around a point \( a \) using derivatives at that point.
