question 50

Multiple Choice

Place your graphing calculator in parametric and degree modes. Set the window for $T \min = 0$ , Tmax=360, Tstep=1, Xmin= -1.8, $\mathrm { Xmax } = 1.8 , \mathrm { Xscl } = 1 , \mathrm { Ymin } = - 1.2 , \mathrm { Ymax } = 1.2 , \mathrm { Yscl } = 1$ . Set the functions to $\mathrm { X } _ { 1 \mathrm {~T} } = \cos \mathrm { T } ^ { \mathrm { m } } , \mathrm { Y } _ { 1 \mathrm {~T} } = \sin \mathrm { T }$ . Graph the circle of radius 1 on the screen. Use the trace feature to move a short distance around the circle.
