Draft V1. This article is a straightforward application of the new pi series combining trigonometry and calculus based on one-2^nth fractions of the disc quadrant described in my previous article: “Applied trigonometric calculus: PI integral series based on powers of 2 fractions of the disc quadrant”. This article show pi’s formal estimation error issued from pi 2^n-sided polygon approximation.
