This shape is the inverse curve of a cardioid. Its three-dimensional analog is given by z over c equals x squared over a squared plus y squared over b squared, and it can be represented in polar coordinates by r equals d over one plus or minus cosine theta.
This shape is the inverse curve of a cardioid. Its three-dimensional analog is given by z over c equals x squared over a squared plus y squared over b squared, and it can be represented in polar coordinates by r equals d over one plus or minus cosine theta. A method of approximating integrals using these shapes is named for Simpson. Light reflected off a mirror with this shape will be focused at a single point. Its eccentricity equals one, and it may be generated by slicing a cone with a plane parallel to a straight line along its surface. For 10 points, name this conic section which is the set of points equidistant from a line and a point, an example of which is y equals x squared.
