# Category:Approximation theory

Computing portal |

Here is a list of articles in the Approximation theory category of the Computing portal that unifies foundations of mathematics and computations using computers.

In mathematics, approximation theory is concerned with how functions can be approximated with other, simpler, functions, and with characterizing in a quantitative way the errors introduced thereby.
