Two Circles

Two circles are plotted on the catersian plane using polar coordinates; r, which is the radius vector is equal to 3 sin θ or 3 sin 30°, 3 sin 45°, 3 sin 60°, 3 sin 90°, 3 sin 120°, 3 sin 135°, 3 sin 150°, and 3 sin 190°

The green circle below is equal to 3 sin θ or - 3 sin 180°, - 3 sin 210°, - 3 sin 225°, and - 3 sin 240°, - 3 sin 270°, - 3 sin 300°, - 3 sin 315°, - 3 sin 330° and - 3 sin 0°.


r = (3 sin Ѳ)

r = ( -3 sin Ѳ)
