Question

Polar coordinates of a point are given. Find the rectangular coordinates of the point. (-5, -180°)

A. (-5, 0)

B. (0, -5)

C. (0, 5)

D. (5, 0) Reset Selection

Answer 1

\(\bf (-5,-180^o)\qquad r=-5\qquad \theta=-180^o\\ \quad \\
x=rcos(\theta)\implies x=-5\cdot cos(-180^o)\\ \quad \\y=rsin(\theta)\implies y=-5\cdot sin(-180^o)\)

Answer 2

get the values, plug them in at (x, y) for the rectangular form
