Wikipedia definition

1. Orthogonal functionsIn mathematics, two functions and are called orthogonal if their inner product is zero for f ≠ g. How the inner product of two functions is defined may vary depending on context. However, a typical definition of an inner product for functions is with appropriate integration boundaries. Here, the asterisk indicates the complex conjugate of f.
