👉 In the context of mathematics, "harns" are a mathematical concept that refers to the collection of all points on a given curve or surface. They are often used in geometry and calculus to represent the general shape of a curve or surface. Harns can be defined by specifying a parametric equation for the curve. For example, if we have a curve described by the parametric equations x(t) = t^2 + 3 and y(t) = t^3 -
