Henri Pade

Henri Padé was a mathematician known for developing Padé approximants, which are methods to approximate complex functions with rational functions (fractions of polynomials). Unlike Taylor series, which are infinite sums that can be limited in accuracy outside a small range, Padé approximants often provide better approximations over a broader domain. This technique is widely used in engineering, physics, and applied mathematics to analyze systems, improve numerical calculations, and model phenomena with greater precision, especially when dealing with functions that are difficult to approximate with simple series expansions.
