Question

107? What are the coordinates of the terminal point determined by t= 3 3 2 2 O (1) A. (3.-2 O B. ( 5, -20 OC.COM O D. (. c D SUBMIT

Answer 1

$t=\frac{10\pi}{3}\equiv\frac{4}{3}\pi$

Therefore:

$\begin{gathered} \cos (240)=\cos (\frac{4}{3}\pi)=-\frac{1}{2} \\ \sin (240)=\sin (\frac{4}{3}\pi)=-\frac{\sqrt[]{3}}{2} \\ (-\frac{1}{2},-\frac{\sqrt[]{3}}{2}) \end{gathered}$
