An example of this shape named for Jakob Steiner shares its center with the centroid of a triangle.
An example of this shape named for Jakob Steiner shares its center with the centroid of a triangle. The inverses of integrals developed to find the arc length of this shape create curves that were mapped to modular forms in the Taniyama-Shimura conjecture. The parametric equations for this shape, with a and b not necessarily equal, are x equals a cosine of t and y equals b sine of t. This shape is commonly drawn by using a piece of (*) string fixed to two pins. This shape has a semimajor and a semiminor axis, as well as an eccentricity between zero and one. For 10 points, identify this shape that resembles a flattened circle.
