i have to draw a flat unit circle all the way to 4 pi in radians. i can get to 2 pi but i have trouble finding the radians if i went one more time around the unit circle.

• trig -

what's the trouble? Just trace the circle twice. If you have to label some points along the way, just label each marked point with two values:

pi/2,5pi/2
and so on
