👉 Polyptya, also known as a biconvex parabola, is a type of conic section that has one focus and two directrices. It is formed by intersecting two circles. The equation of a polyptya can be expressed in terms of the distances from any point on the curve to its endpoints, which are both vertices of the circle. The general form of a polyptya's equation is: \[ x^2 - 2ax + y^2 =
