1. A recursive method for computing numerical values for mathematical functions, comprising: providing a recursive Taylor series representation of a mathematical function f(x) of a variable x around a given operating point a, wherein said recursive Taylor series representation includes a plurality of derivative derived terms that include ratios of derivatives of said mathematical function evaluated at said operating point a; determining coefficient data comprising ones of said plurality of derivative derived terms evaluated at said operating point a over a predetermined range, wherein said plurality of derivative derived terms are stored in a tangible memory device, and computing an approximation for said mathematical function f(x) using said recursive Taylor series representation evaluated with said coefficient data, wherein said computing is implemented with a computational architecture that includes a plurality of multipliers.
