PREFACE

The traditional Pi value of 3.1415 is found in many formulae in trigonometry and geometry, especially those concerning circles, ellipses, and spheres. Geometry is one of the oldest branches of mathematics. It is concerned with properties of space that are related to distance, shape, size, and relative position of figures. Until the 19th century, geometry was almost exclusively devoted to the fundamental concepts of Euclidean geometry, which includes the notions of point, line, plane, distance angle surface, and curve. Later in the 19th century, the scope of geometry has been greatly expanded, and the field has been split into many subfields that were known as combinatorial geometry. Other scholars used various mathematics equations to shape the circumscribed polygon into an inscribed circle by using an ever-increasing number of polygon sides to add more decimal places into the traditional Pi value of 3.1415. Indeed the Pi has been known for almost 4000 years, but even if the number of minutes that elapsed since then the calculated Pi to that number of many decimal places added to the 3.1415 is still only approximating its actual value.

ABSTRACT

The author of this book has discovered an innovative method of determining the True value of Pi (π = 39604.png = 3.1623 or 3.16227766016838). This new Pi value is derived from the geometric relationships among the circle’s components with the use of the Circle Theorem and Pythagorean Theorem. Figure 1 contains an inscribed circle in the square consisting of gridlines equally spaced into one-fourth of the side of the square or the diameter of the inscribed circle. The resulting precise Pi value is validated with the use of the Polygon Area formula, Binomial Theorem, and Quadratic Equation. This contemporary approach to finding the true Pi value reputes the traditional method of finding the Pi value which represents the ratio between the circumference and the diameter. For the past four centuries, many mathematicians have attempted to find the precise Pi value. It began with measuring the circumference and the diameter of a circle and dividing the former by the latter. The Pi calculation began during the era of Archimedes of Syracuse circa 287–212 before the Christian
