Question

How do you find the rectangular coordinates given the polar coordinates `(3, pi/2)`?

Answer 1

Use `x = rcos(theta) and y = rsin(theta)`. Please see the explanation.

Explanation:

Use the equations:

`x = rcos(theta) and y = rsin(theta)`

`x = (3)cos(pi/2) and y = 3sin(pi/2)`

`x = 0 and y = 3`

The point is `(0,3)`
