👉 Cycloid, a type of conic section in three dimensions, is defined as the locus of points that move so that their distance from a fixed point (the center) remains constant throughout their journey. This means that the distance between any two points on the curve changes at exactly one time, which can be described mathematically as: d = r + s where d is the distance traveled by a point in the cycloid, r is the radius of the circle traced out by a
