$(0, 2)$ $( 0 , 2)$

For polar coordinates we have: $(r, θ)$ $(r,theta)$

For Cartesian coordinates we have $(x, y)$ $(x,y)$

$x = r cos (θ)$ $x=rcos(theta)$

$y = r sin (θ)$ $y=rsin(theta)$

$x = 2 cos (\frac{- 15 π}{2}) = 0$ $x=2cos((-15pi)/2)=0$

$y = 2 sin (\frac{- 15 π}{2}) = 2$ $y=2sin((-15pi)/2)=2$

$:.$

Cartesian coordinates:

$( 0 , 2)$

What is the Cartesian form of ( 2 , ( - 15pi)/2 ) (2,−15π2)( 2 , ( - 15pi)/2 ) ?
