Rational inequalities. Since ellipses are curves, it makes sense to use a coordinate system that is curved. A way to think about this is is that you want to shift all $\theta$ to $\theta'=\theta +\delta$, where $\delta$ is the amount by which you want to rotate. 9 Distance and Midpoint Formulas; Circles.
