Cysoid (green) formed by curves r = θ and r =

Cysoida - type of flat curve.

It is based on two other curves. If they are in the polar coordinate system of the equation r = f 1 ( θ ) {\displaystyle r=f_{1}(\theta )} r = f 2 ( θ ) {\displaystyle r=f_{2}(\theta )}

The equation for their cysoids is: r = f 1 ( θ ) & # x2212; f 2 ( θ ) {\displaystyle r=f_{1}(\theta )-f_{2}(\theta )}

The most well-known curve of this type is the Dioclesian Cyxide, which is a circle and straight circle. Comments
