A much easier and intuitive approach is via area inside those graph-squares where the great-circle splits a square apart and where the tractrix splits the square apart. Your approach is more from the engineering standpoint. Mine is more from pure math. Yours goes into elasticity and bending. Mine seeks just pure relationships. So in my approach, I want to examine all the graph-squares and see if there is any square which the arc of the circle is matched in area by the arc of the tractrix as it splits that square into two parts. If it matches exactly in area, then the arcs are equal. So I simplified my task and chore to finding where the area of the tractrix square is 90% the area of the circle square. I think you would agree that I made the problem far more esthetically pure, rather than introduce a strain and bending concept which would be the only route for an engineer, since an engineer is not after the pure-knowledge but rather the practical. By the way, I am after this, for the ulterior motive that 10% of the tractric is equal or close to equal to the great-circle, for the idea that Algebra is only good for about 10% of all the numbers and that Algebra is deaf dumb and silent over 90% of the numbers that exist. So, I have what I sought for, and time to move onwards. Archimedes Plutonium www.iw.net/~a_plutonium whole entire Universe is just one big atom where dots of the electron-dot-cloud are galaxies
