Tim Wesserman or Edward Shore
I do ask this of 2 great minds? Here is the deal, I need to extend the function atan2(y,x). It is in FORTRAN and I have no idea about that. Attached is a function that with computational ease keeps track of coordinates on a sphere much faster than current computational times.
It is because of you 2 that I understood the programming language of HP Prime to define some functions. These functions were part of ancient trigonometry that is well studied and well behaved. It is a bit computationally heavy for humans, but if we allowed for billions of iterations a second, the best choice of methods is this for sure. Versin(x), EXESEC(x), and so on..... The F is for Folium of Descartes. If I had never read you 2 I could have never answered the question "What is the derivative of CVCSIN(x)", why, "Because I want to know". Adam |
