Fourier Series 2
Fourier Series 2 : A series proposed by the French mathematician Fourier about the year 1807. The series involves the sines and cosines of whole multiples of a varying angle and is usually written in the following form: y B 12 3 1 2 =A + A sin x + A sin 2x + A sin 3x + .. B cos x + B 3 cos 2x + B cos 3x + ..By taking a sufficient number of terms the series may be assumed to represent any periodic function of x
