Then which of the following holds. a) AM = 5 b) AM =- 5 c) AM = 5 d) AM = 5 e) AM =- 5 T =- T = T = T = T = 2 = 4 = 2 = 4 =- 4 =- 2 2. Suppose = cos- 1- 3 5 . Choose the appropriate diagram corresponding to the angle in standard position. 3. cos- 1 (cos ) = True False 4. sin - 2 = cos True False Given a = sin- 1 b answer the following 5. a is an angle True False 6. b is an angle True False SHOW ALL YOUR WORK. Answers without procedure will be graded zero. [15 points] II. FREE RESPONSE [4 pts] 1. Suppose we have y = A sec( ( x- )), where A = 4, = 2 , =- 1 4 and hence the period T = 2 = 1. Sketch the graph of the function y with this characteristics. *Recall you may first find the corresponding cosine graph....
