# Special functions facts for kids

**Special functions** are some mathematical functions used in mathematical analysis or physics. Most of them appear in higher education. Some experts are studying numerical methods for them.

## Definition

In mathematics, most functions are defined as a solution of a differential equation. For example, the exponential function is the solution of the ordinary differential equation . Due to this relation, some mathematicians are studying the connection between ODEs and special functions.

## Examples

- Gamma function, it is studied since Euler
- Orthogonal polynomials, these are polynomials with special properties.
- Matrix functions, these are studied in linear algebra and matrix analysis.

For more examples, find textbooks named "special functions".
