The cartesian point is (0,5).

Explanation:

x=rcos(θ) and y=rsin(θ) and for the given point r=5 and θ=3π2.

x=5cos(3π2)=50=0
y=5sin(3π2)=5(1)=5

So the cartesian point is (0,5).

(0,5)

Explanation:

to convert from polar to cartesian form

that is (r,θ)(x,y) where

xx=rcosθ and y=rsinθ

here r=5 and θ=3π2

x=5×cos(3π2)=5×0=0

y=5×sin(3π2)=5×1=5

(5,3π2)(0,5)
