Journal ArticleDOI
Birth, growth and computation of pi to ten trillion digits
TL;DR: The universal real constant pi, the ratio of the circumference of any circle and its diameter, has no exact numerical representation in a finite number of digits in any number/radix system as mentioned in this paper.

Approximations to π Derived from Integrals with Nonnegative Integrands
TL;DR: In this paper, Lucas et al. derived approximate approximations to π derived from integrals with nonnegative integrands, and used them to obtain a nonnegative approximation of π.

Yet Another Table of Integrals.
TL;DR: In this article, a collection of sums and integrals has been harvested from the mathematical and physical literature in unstructured ways, and its main use is backtracking the original sources whenever an integral of the reader's application resembles one of the items in the collection.

Understanding the Concept of the Pi (π) Number for Elementary School of Pre-Service Teacher
TL;DR: In this article, a case study was conducted by employing case study method containing a single case concerning the Pi numbers (π), where a total of 432 pre-service teachers participated in the study from the academic year of 2019-2020.

A first course in mathematical analysis, by David Brannan. Pp. 459. £24.99. 2006. ISBN: 978 0 521 68424 8; 10: 0 521 68424 2 (Cambridge University Press, in association with the Open University).
TL;DR: Morris as mentioned in this paper introduced the notion of natural algebras of matrices that give rise to higher dimensional geometric spaces and showed that in 2-dimensions, every non-zero complex number can be represented as (x y, I a b).
