Abstract
Es bastante conocido que el número irracional "pi", de amplia aplicación en las matemáticas, es la razón entre la longitud de una circunferencia y el diámetro que esta genera. Sin embargo hay otra forma de entender a este número, a través del cálculo de la superficie de una parte de la circunferencia y esto se logra con el uso de herramientas del cálculo integral. El método utilizado para este propósito: es el análitico matemático, y el resultado obtenido es la verificación de la propuesta establecida. Se pretende por tanto, verificar que la integral de una función, definida en un intervalo determinado, resulta ser el número "pi". Luego de una serie de consideraciones, operaciones matemáticas y cálculos, al final del trabajo se obtiene el resultado esperado. Por tanto, la superficie de media circunferencia es el número "pi" y, esta es una interpretación alternativa, no aritmética de esta importante constante matemática.
It is well known that the irrational "pi, of wide application in mathematics, is the ratio between the length of a circumference and the diameter that this generates. However there is another way of understanding this number, this is through the calculation of a part of the circumference and this is done with tools of integral calculus. The method used for this purpose is the mathematical analysis, and the result obtained is the verification of the established proposal. It intends to verify that the integral of a function over a given interval, also turns to be "pi" number. Carried out some considerations, mathematical operations and calculations, ay the end of this paper, the expected result is reached. Therefore, the surface of a half circumference is also the "pi" number, this is an non arithmetic alternative interpretation of this fundamental mathematical constant.
