Theorem
Let $\EE$ be an ellipse embedded in the plane.
Let $P$ be an arbitrary point in the plane.
Let $\LL$ be the polar of $P$ with respect to $\EE$.
Then $\LL$ is the locus of harmonic conjugates with respect to $\EE$.
Proof
This theorem requires a proof. In particular: Need to craft the definition of harmonic conjugates with respect to $\EE$. See Harmonic Property of Pole and Polar wrt Circle and explore what Sommerville says about this in chapter $\text {III}$ section $5$. You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof. To discuss this page in more detail, feel free to use the talk page.
