This animation shows two forgotten trigonometric functions: the versine and the coversine. These come from lengths in the unit circle that measure the horizontal/vertical distance between the edge/top of the circle and the cosine/sine coordinates on the axes. These can easily be written in terms of sine and cosine, so they are not really used anymore; they were primarily used to build tables of values when 1-cos(theta) and 1-sin(theta) were needed to various precision that would take too long to compute when those values are close to zero.
