The following H.W. Project is Due April 19, 2011 will guide you through the process of doing several of these derivations. Complete the following… Sign the Honor Statement: "On my honor, I have neither given nor received unauthorized aid in doing this assignment."

Let ¦ and § be arbitrary angles (that means they can be anything ). The following diagram shows the unit circle with several angles, rays, terminal points, and line segments outlined. Do: In the following observations circle or underline the correct choice to make the observation true. Observe: The angle ¦ [ is / is not ] in standard position and its amount of rotation is labeled with the color red . Observe: The angle – § [ is / is not ] in standard position and its amount of rotation is labeled with the color blue . Observe: The angle ¤ [ is / is not ] in standard position and its amount of rotation is also labeled with the color blue ....
