This paper is geared towards the students and admirers of Sir Isaac Newton, to assert by this paper, almost after 400 years; to remind him and them; that it is mathematically imprecise to calculate a curve or area of a circle, without the parity of numbers equations with correct trigonometry and equations of numbers, aligned to the great theorem of Pythagoras, specially Pythagoras 1:3, which is the keel of the universe of mathematics at subtended angle 360/19 degrees. The inverse curvature of the universe of mathematics ( Universe itself) is precisely related to Pythagoras 1:1; 1:3 ; 1:5 as shown in this paper using the correct value of 360/19 degrees at Pythagoras 1:3; is easily mathematically plotted and as herein published, and Newton’s ...
