In this activity, students must become familiar with the unit circle as they evaluate different trigonometric expressions (without using a calculator). Angles are given in radians. In the process, they match their answer to an answer bank and solve the joke "Why is it a bad idea to hang a funny picture on the wall?" The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle.
