Use a calculator to convert from polar to rectangular coordinates. Round to the nearest hundredth.
-(4.0, -33°)

Question

Quizplus · Accepted Answer

To convert from polar to rectangular coordinates, use the formulas $x = r\cos(\theta)$ and $y = r\sin(\theta)$. For $r = 4.0$ and $\theta = -33^\circ$, $x = 4.0 \cos(-33^\circ) \approx 3.35$ and $y = 4.0 \sin(-33^\circ) \approx -2.18$, making the correct answer (3.35, -2.18).
