Unformatted text preview: Name: Version A MAC 1114 Test 2 10/23/2007 SHOW ALL YOUR WORK. Answers without procedure will be graded zero. [5 points] I. MULTIPLE CHOICE 1. For y =- 3 tan(- 2 x + π 2 ), suppose A =amplitude, T =Period and φ ω = phase shift. Then which of the following holds. a) A = 3 b) A =- 3 c) A = 3 d) A = 3 e) A =- 3 T =- π 2 T = π 2 T = π 2 T = π 2 T = π φ ω = π 4 φ ω = π 2 φ ω = π 4 φ ω =- π 4 φ ω =- π 2 2. The exact value of cos- 1 (- √ 3 2 ) is a) π 6 b)- π 6 c) 7 π 6 d) 5 π 6 e) 2 π 3 3. Suppose θ = tan- 1 3 2 . Choose the appropriate diagram corresponding to the angle θ in standard position. 4. tan(tan- 1 x ) = tan- 1 (tan x ) for all x in the Real numbers True False 5. sin(sin- 1 π ) = π True False 6. sin π 2- θ = cos θ True False [1 pt extra credit] In problem 4, explain why. [19 points] II. FREE RESPONSE [6 pts] 1. Suppose we have y = A sec( ω ( x- φ ω )), where A = 2, ω = 2 π , φ ω =- 1 2 and hence the period T = 2 π ω = 1. Sketch the graph of the function= 1....
