This paper presents a systematic technique for approximating the area of a curvilinear region using easy to calculate polygonal areas.

This paper presents a set of rules that serve to express the numbers.

A determinant is mathematical notation consists of a square table of numbers, or others elements between two vertical lines, the expression value is calculated by following certain rules development

In this work, the operations can be performed on propositional calculus that are the basis for the study of the logic and how computers work.

This presentation shows and defines the different types from Models that the Investigation of Operations works.

This work focuses on the theme of the conjunction but with logic gates, it will show the equivalence existing in traditional logic with binary logic.

In this work we present the molecular propositions topic dilemmas that belong equally to propositional logic, which are very important for subsequent application in the construction of switching circuits.

In this work we present the last of the three most important propositions in propositional calculus which is the negation of a proposition, the negation is widely used in switching circuits.

This work focuses on the theme of disjunction with their equivalent in Boolean algebra for building digital circuits and the analysis of binary signals.

When modeling problems in science, engineering and economics are ordinary differential equations frequently. An ordinary differential equation (ODE hereafter) is a relationship between an independent variable and a ...
