In this patent application, we propose a System and Method for computing the algebraic (mathematical) sum of two or more numbers. As examples of the efficacy of the System and Method, we propose to compare the results of the algebraic (mathematical) sum of the numbers 2 and 2 according to the proposed Method, as compared with the methods widely used by previously known procedures, which would frequently under- or overestimate the result by a great margin. We also estimate the value of the Mathematical Constant Euler's Pi as 3.109, which is slightly smaller than the previously accepted value. The reduction in the value of the Mathematical Constant Euler's Pi will allow us to economize up to 1% of raw materials used in producing spherical laboratory glass and other equipment of spherical shape.

На что автор отвечает, что не использует трапеций, а только прямоугольники и треугольники. Еще выясняется, что этот метод подсчета уже получил название: Tai's Model

Date: 2013-08-26 01:05 pm (UTC)Yes, thankfully, somebody commented that "Although we do not have a first reference, it is our understanding that the trapezoidal rule was known to Isaac Newton in the 17th century. "
The author answers:
I have presented the original concept into a functioning mathematical description that can be easily observed and applied. I therefore carefully named the mathematical description as Tai's "model" rather than "formula" to indicate that I have used existing formulas for small area calculations.
You see, M. M. Tai's unique contribution is that she "presented the concept into a description" (whatever that phrase means). It's a "model" and not a "formula" for the area. It's a "model" because she was using formulas to compute something specific (areas under metabolic curves), not just to write a formula. Newton just wrote the formula without thinking much; it's only M. M. Tai who finally realized that the trapezoidal rule can be used to compute areas under metabolic curves.
Another comment was that the precision of M. M. Tai's model was not adequately investigated. She answers:
Because Tai's model is based on the calculations of individual squares and triangles, its precision is obviously absolute.
Right. So this is a model of absolute precision.
