👉 In mathematics, a Peninvariant is a function that satisfies certain properties when plotted on a surface. These functions are known as Peninvariants and they can be used in various fields such as physics, chemistry, engineering, and even computer graphics. A Peninvariant is a continuous function f defined on the real line that has the following properties: 1. It is differentiable at every point x on its domain. 2. The derivative of f(x) with respect to x exists for all values
