Place Your Graphing Calculator in Parametric and Degree Modes $\mathrm { Tmin } = 0$

question 155

Multiple Choice

Place your graphing calculator in parametric and degree modes. Set the window for $\mathrm { Tmin } = 0$ , $\mathrm { Tmax } = 360$ , $\mathrm { Tstep } = 1 , \mathrm { Xmin } =$ $- 1.8 , X _ { \max } = 1.8 , \mathrm { Xscl } = 1 , \mathrm { Ymin } = - 1.2 , \mathrm { Y } \max = 1.2 , \mathrm { Y } \mathrm { scl } = 1$ . Set the functions to $\mathrm { X } _ { 1 \mathrm {~T} } = \cos \mathrm { T } , \mathrm { Y } _ { 1 \mathrm {~T} } = \sin \mathrm { T }$ . Graph the circle of radius 1 on the screen. Use the trace feature to move a short distance around the circle.
-For what angle $\mathrm { T }$ is $\sin \mathrm { T } \approx 0.174$ ? (Assume $0 ^ { \circ } \leq \mathrm { T } \leq 90 ^ { \circ }$ .)

• A) \(56.422 ^ { \circ }\)
• B) \(0.174 ^ { \circ }\)
• C) \(10 ^ { \circ }\)
• D) \(80 ^ { \circ }\)
