👉 In mathematics, a cassinoid is a type of conic section that arises in the context of solving problems involving algebraic equations. It is named after the mathematician Johann Heinrich Cassini. A conic section is a curve that can be described by an equation in two variables, x and y, which has a particular form when plotted in the Cartesian plane. The most famous example of a cassinoid is the ellipse given by the equation: x^2/a^2 + y
