Question

Find the corresponding point on the unit circle for the radian measure given below. 0=20pi/3

Answer 1

$\theta =\cfrac{20\pi }{3}\implies \theta =\cfrac{6\pi +6\pi +6\pi +2\pi }{3} \\\\\\ \theta =\cfrac{6\pi }{3}+\cfrac{6\pi }{3}+\cfrac{6\pi }{3}+\cfrac{2\pi }{3}\implies \theta =2\pi +2\pi +2\pi +\cfrac{2\pi }{3}$
