Answer 1

For this problem recall the formula for polar to rectangular conversion is
$x = r \cos(theta)$
$y = \sin(theta)$
and the polar coordinates are in the form
note: the dot is a substitute for the comma
$(r.theta)$
so to find our coordinates we just need to plug our values of theta in
$x = \cos( \frac{2\pi}{3} )$
$y = \sin( \frac{2\pi}{3} )$
simplify and we get this as our final answer

$( \frac{ - 1}{2} . \frac{ \sqrt{3} }{2} )$
