12. Task: Create a unit circle by applying it to any object (paper plate, pizza, flower, clock, etc.). Write a description of how the sine curve and the cosine curve is derived from the unit circle. In addition, create a problem where the unit circle is used to solve trigonometric problems (Refer to Chapter 3 and Chapter 4). Due: 12/01/14
