👉 In mathematics, the term "gonidial" refers to a mathematical object or function that is defined by its derivative with respect to one of its variables. This can be applied to various fields such as calculus, optimization, and differential equations. For example, in calculus, a "gonidial" function may represent a rate of change in the position of an object, such as velocity or acceleration. In optimization problems, it might represent a function that minimizes some objective function under certain constraints,
