First we will fill the table

t x=cos t y=sin t (x,y)

0 1 0 (1, 0)

π/4 0.707 0.707 (0.707,0.707)

π/2 0 1 (0,1)

3π/4 -0.707 0.707 (-0.707,0.707)

π -1 0 (-1,0)

5π/4 -0.707 -0.707 (-0.707,-0.707)

3π/2 0 -1 (0,-1)

7π/4 0.707 -0.707 (0.707,-0.707)

2π 1 0 (1,0)

Then we graph each ordered pair and we obtain the graph of the unit circle
