👉 In mathematics, a laurent series is a power series where each coefficient represents a function evaluated at a given point. These functions are usually polynomials or rational functions with coefficients in a field of characteristic zero.
For example:
1. For the function f(x) = x^3 - 2x + 1, we have:
$$f(x) = \sum_{n=0}^{\infty} C_n (x-a)^n$$
where C_n are
