According to Theon of Alexandria, who worked in Alexandria as a teacher of mathematics and astronomy, Hipparchus wrote a treatise in twelve books on chords in a circle, which has been lost (Sarton 286). In fact, in real life when something is pushed towards a central point in proportion to its distance from that point (as in pendulum s, weights on spring s, molecule s trapped in solid s, and musical instruments - we call this ' simple harmonic motion ') it will indeed move in a sine curve, which is why trigonometry is the mathematics of oscillation s as well as triangles and circles.
