Generalizations of the derivative | Convex optimization | Variational analysis
In mathematics, the subderivative, subgradient, and subdifferential generalize the derivative to convex functions which are not necessarily differentiable. Subderivatives arise in convex analysis, the study of convex functions, often in connection to convex optimization. Let be a real-valued convex function defined on an open interval of the real line. Such a function need not be differentiable at all points: For example, the absolute value function f(x)=|x| is nondifferentiable when x=0. However, as seen in the graph on the right (where f(x) in blue has non-differentiable kinks similar to the absolute value function), for any x0 in the domain of the function one can draw a line which goes through the point (x0, f(x0)) and which is everywhere either touching or below the graph of f. The slope of such a line is called a subderivative (because the line is under the graph of f). (Wikipedia).
Calculus with integral polynumbers | Arithmetic and Geometry Math Foundations 70 | N J Wildberger
We introduce calculus in the context of integral polynumbers: first by reviewing Pascal's Array and binomial coefficients, and then explaining why the Taylor bipolynumber of a polynumbers can be obtained by suitably multiplying diagonals of this array by the coefficients. The derivative an

Calculus on the unit circles | Arithmetic and Geometry Math Foundations 78 | N J Wildberger
We illustrate algebraic calculus on the simplest algebraic curves: the unit circle and its imaginary counterpart. Starting with a polynumber/polynomial of two variables, the derivation of the Taylor polynumber, subderivatives, Taylor expansion around a point [r,s] and various tangents are

Subderivatives and Lagrange's Approach to Taylor Expansions | Algebraic Calculus Two | Wild Egg
