Category:Polar Subnormals

This category contains results about Polar Subnormals.
Definitions specific to this category can be found in Definitions/Polar Subnormals.

Let $\CC$ be a curve embedded in a polar plane.

Let $\PP$ be a given point on $\CC$.

Let $\RR$ be the straight line through the pole $O$ perpendicular to the radius vector of $\PP$.

The polar subnormal of $\PP$ with respect to $\CC$ is the projection of the polar normal of $\PP$ with respect to $\CC$ onto $\RR$.
