Intermediate Topic 34 of 51 Math for Computing

Taylor Series

Approximating functions by polynomials.

How it works

A smooth function is approximated near a by Σ f⁽ⁿ⁾(a)(x−a)ⁿ/n!; e^x = 1 + x + x²/2! + …; truncation error is bounded by the next term.

Where it is used

Numerical methods, deriving algorithms.

Common pitfall

Series converge only within a radius.
