Polar coordinates $(- 2, π)$ $(-2,pi)$ in rectangular coordinates are $(2, 0)$ $(2,0)$

Explanation:

Normally $r$ $r$ in polar coordinates $(r, θ)$ $(r,theta)$ are positive, but many times $- r$ $-r$ is allowed and is taken in opposite direction to that indicated by $θ$ $theta$ i.e. $θ + π$ $theta+pi$ .

Further, polar coordinates $(r, θ)$ $(r,theta)$ in rectangular coordinates are $(r cos θ, r sin θ)$ $(rcostheta,rsintheta)$

Hence polar coordinates $(- 2, π)$ $(-2,pi)$ in rectangular coordinates are

$(- 2 cos π, - 2 sin π)$ $(-2cospi,-2sinpi)$ or $(- 2 \times (- 1), - 2 \times 0)$ $(-2xx(-1),-2xx0)$ i.e. $(2, 0)$ $(2,0)$
