Gaussian function
In mathematics, a Gaussian function, often simply referred to as a Gaussian, is a function of the base form with f(x) = exp(-x^2) and with parametric extension f(x) = aexp(-(x-b)^2)/2c^2) for arbitrary real constants a, b and non-zero c.
Fourier theorem
A Fourier series is an expansion of a periodic function into a sum of trigonometric functions.
