Place your graphing calculator in parametric and degree modes. Set the window for Tmin=0, Tmax=360, Tstep=1, Xmin= $- 1.8 , X _ { \max } = 1.8 , X _ { \text {scl } } = 1 , Y _ { \min } = - 1.2 , Y \max = 1.2 , Y \mathrm { scl } = 1$. 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.
