The coordinates in rectangular form are $(0,1)$ .

Given a polar coordinate of the form $(r, theta)$ , the conversion formula to rectangular/cartesian form is:
$x = rcos(theta)$
$y = rsin(theta)$

In the case of your given coordinates:
$x = cos(pi/2) = 0$
$y = sin(pi/2) = 1$

So the coordinates in rectangular form are $(0,1)$ .
