<em>Additional comment</em>
It will be worth your time to learn to recognize the sine and cosine functions. They have a maximum of +1, a minimum of -1 and a period (horizontal distance between corresponding points) of 2π. The sine function is symmetrical about the origin. The cosine function is symmetrical about the y-axis. The maximum slope (near the zero-crossings) is 1.
