n

(Mathematics) an infinite trigonometric series of the form ½a₀ + a₁cos x + b₁sin x + a₂cos 2x + b₂sin 2x + …, where a₀, a₁, b₁, a₂, b₂ … 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
