Name: Version A MAC 1114 Test 1 09/24/2009 Recall that: s = A = 1 2 r 2 θ ω = θ t v = s t v = [6 points] I. MULTIPLE CHOICE (True and false are half a point each) 1. One revolution is equivalent to π radians True False 2. The reference angle of θ is the angle the terminal side of θ makes with the x-axis True False 3. sec 2 θ = 1 - tan 2 θ True False 4. csc θ is defined on the x - intercepts of cos θ True False 5. The angle θ = 63 π 42 in radians is equivalent to how many degrees? a) 270 b) 90 c) - 90 d) 1 120 e) 3 π 2 6. The point on the xy - plane with coordinates ( - 2 , 0 ) can be used to compute the value of the trigonometric functions for the angle θ = 7. Given y = cos( πx + 2), suppose T =Period and φ = phase shift of y , then which of the following holds. φ = - 2 π φ = 2 π φ = - 2 π φ = - 2 φ = 2

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
