Which set of rectangular coordinates describes the same location as the polar coordinates (4, 3pi/2)

(0,-4)

Step-by-step explanation:

To convert from the polar coordinates to rectangular coordinates use;

and

The given polar coordinate is;

This implies that;

r=4 and

We substitute to obtain;

and

and

(0,-4)

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
