Answer:
Actually, the graphs of functions defined by y = sin x are called sine waves or sinusoidal waves. Notice that the graph repeats itself as it moves along the x-axis. ... This graph repeats every 6.28 units or 2 pi radians. It ranges from -1 to 1; half this distance is called the amplitude. The purpose is :Triangulation a process that works by using the distance from two known points, is used in cell phones equipped with GPS. A GPS receiver measures distance using the travel time of radio signals from satellites. Sine and cosine functions are used to find the location and distances in the GPS system of the cell phone.
