Place Your Graphing Calculator in Parametric and Degree Modes $- 1.8 , \mathrm { X } \max = 1.8 , \mathrm { Xscl } = 1 , \mathrm { Ymin } = - 1.2 , \mathrm { Ymax } = 1.2 , \mathrm { Yscl } = 1$

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