Cos and sine relationship
WebJan 21, 2024 · Properties of the sine and cosine functions Because the sine function results from tracking the y -coordinate of a point traversing the unit circle and the cosine function from the x -coordinate, the two functions have several shared properties of circular functions. Properties of the sine and cosine functions.
