Rose Curve with Three Petals

 

 r = 3 sin θ  

A rose curve with three petals

 

3 amplitud and period 2π /3

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)

The Circunference

 The circunference is plotted on the catersian plane using polar coordinates; r, which is the radius vector is equal to 4 sin θ or 4 sin 0°, 4 sin 30°, 4 sin 45°, 4 sin 70°, 4 sin 90°, 4 sin 110°, 4 sin 135°, 4 sin 150° and 4 sin 180°.
