@holvek: The Nephroid is a kidney-shaped plane curve that belongs to the epicycloid family. It is generated by the path of a fixed point on a circle that rolls without slipping around the outside of a fixed circle of twice its radius. The name originates from the Ancient Greek words for "kidney" and "shape", and its mathematical structure is defined by a sixth-degree algebraic equation. In physics and optics, the nephroid is famous as a caustic — the envelope of light rays reflected by a circular mirror. This optical phenomenon is easily observed in daily life, appearing as a bright, kidney-shaped pattern at the bottom of a teacup or coffee mug when parallel light reflects off its inside walls. Mathematically, the nephroid possesses perfect symmetry, features two sharp points called cusps, and encloses an area equal to 12π r², where r is the radius of the rolling circle. The total arc length of the entire curve is exactly 24r, making this seemingly complex shape surprisingly elegant and proportional in its geometric properties. #mathematics #fact #education #school

Смотрите принцип квадрата:вот 2 во 2 это 4 , а 3 будет прошлый результат(4) + 5 то есть каждый раз прибавляем нечетное число будет 9 , это работает , проверьте!
