👉 In mathematics, a "rougeaux" (or "rondant") is a type of polynomial function that has a series expansion in terms of powers of $x$. Specifically, it's defined as follows: A "rougeaux" is a polynomial with the form: \[ f(x) = \sum_{k=0}^{n-1} c_k x^k, \] where $c_0, c_1, ..., c_n$ are constants and $
