TL;DR: In mathematics and its applications one often needs to find a continuous function at a finite (or countable) set of points taken from its domain of definition.

TL;DR: In this paper, the authors introduce functions and graphs with MAPLE, a class of graphs of tabular and continuous functions graphs of composed functions interpolation of functions smoothing of functions.

TL;DR: This concise text on geometry with applications in a variety of disciplines is devoted to three main geometrical topics: curves, surfaces, and polyhedra, and presents elementary methods for analytical modeling and their visualization, as well as demonstrating the potential of symbolic computational tools to support the development of analytical solutions.

TL;DR: In this article, the authors generalize known integral formulae (due to Brito-Langevin-Rosenberg, Ranjan and the second author) for foliations of codimension 1 or unit vector fields and obtain an infinite series of such formulAE involving invariants of the Weingarten operator of a unit vector field, of the Jacobi operator in its direction, and their products.
