RE: Using HP-65 Sunrise/Sunset
Always EAST and SOUTH -ve.
Convention and the way the sin/cos great circle, intermediate latitude and rhumb line formula work. Re-check the TI program for sign convention. They must have a routine to change the sign because I am positive that all rhumb line and great circle formulae require EAST and SOUTH to be -ve. Geoff |
