: If I understand you well, you want to calculate and store the coordinates of the end-points of two "legs", given:
: - the distance between the points and the "origin" (0,0);
: - and the angles that the legs make with the X-axis.

: ( and so on...)

: ...forgive my curiosity ;-) why do you want to store these results in a database, for later recall? Why not you calculate them at the moment you need them, instead of reading the stored results from a slow database on disk?

A legitimate question, the purpose of storing these coordinates in a database is to preserve them for plotting land boundaries, determining areas, tying into other coordinate systems, perpetuate boundary corner or monuments, etc. These are just a few of many reasons to store these coordinates but just as important as all the above, is the ability to recall and inverse between two sets of coordinates to solve for bearing and distance.
I have not had a chance to review what you sent me but will review it tomorrow and get back in touch.
