Added two helper functions to scale values from a true coordinate grid to that of the screen where the screen has location determined by pixel and the true coordinate grid is that of a standard Cartesian grid from 0 < t < 2pi. The getCoordinates() returns an in array of the y values to plot to generate the sine wave.
