Fourier series | |
—n | |
an infinite trigonometric series of the form ½a_{0} + a_{1}cos x + b_{1}sin x + a_{2}cos 2x + b_{2}sin 2x + …, where a_{0}, a_{1}, b_{1}, a_{2}, b_{2} … are the Fourier coefficients. It is used, esp in mathematics and physics, to represent or approximate any periodic function by assigning suitable values to the coefficients |
Fourier series
An infinite series whose terms are constants multiplied by sine and cosine functions and that can, if uniformly convergent, approximate a wide variety of functions. |
