The Fourier transform, S(f) (in blue), which depicts amplitude vs frequency, reveals the 6 frequencies (at odd harmonics) and their amplitudes (1/odd number). Ptolemy, together with the earlier writers, used a form of the relation sin2x+cos2x=1\sin^{2} x + \cos^{2} x = 1, although of course they did not actually use sines and cosines but chords.Similarly, in terms of chords rather than sin and cos, Ptolemy knew the formulas sin(x+y)=sinxcosy+cosxsiny\sin(x + y) = \sin x \cos y + \cos x \sin yasinA=bsinB=csinC\Large\frac {a}{\sin A}\normalsize = \Large\frac {b}{\sin B}\normalsize = \Large\frac {c}{\sin C}.Ptolemy calculated chords by first inscribing regular polygons of 3, 4, 5, 6 and 10 sides in a circle. 2. what it is, who its for, why anyone should learn it.
