For 10 points, name these conic sections often referred to as ovals.
The "super" form of these shapes are modeled by the absolute value of x over a to the n plus the absolute value of y over b to the n equals one, and are Lame curves. These shapes can be drawn by the trammel of Archimedes, and their parametric equations take the form x equals a cos of t and y equals b sin of t. They may be defined as the set of all points equidistant from two foci. Kepler's first law states that a planet's orbit takes this shape. As their eccentricities decrease from one to zero, they approximate circles. For 10 points, name these conic sections often referred to as ovals.
