f4iteightiz/ellipse_iso_perimeter

Few programs in RPN/FOCAL (HP41) for ellipse perimeter calculation and isoperimeter points calculation in the area (0-pi/2). Some calculations are made by infinite series or convergence series (AGM and MAGM). Some calculations are made with modified cycloids or modified conics. The concept of cosinus elliptique is introduced. One program in python for graphic representation of 3D isoperimetrics (a and b in X-Y and perimeter in Z).
