I posted this about a week ago and havn't seen any responses to it.
Since we were having all sorts of news problems at the time, I'm not sure
if it didn't get out, or if it's simply that nobody responded. At any
rate, here goes again (sorry if you've seen this already).
Is there any way to make a HP-48sx display 2-D vectors, when in
polar mode, with the phase angle normalized to 0 <= theta < 360 instead of
the standard -180 < theta <= 180?

I'm faily sure there isn't any way built in. There isn't a flag for it and thats probably where it would be. Fortunately it will let you enter them that way. Incidentally, not that I'm rapping on you but is there a particular reason for wanting them that way. Some strange calculation method or something. Doesn't seem too hard when writing down answers to just add 360 to the HP result? ====================================================================== ___ :__) _ _: _ _ Tim Strong <tdstrong%mtus5.bitnet@cunyvm.edu> : \ (_: (_: (_: : Michigan Tech.

I asked about normalizing vectors to [0,360) instead of (-180,180] and TDSTRONG%MTUS5.BITNET@CUNYVM.CUNY.EDU (Tim Strong) replied: > is there a particular reason for wanting them that way?

The compass is marked off in 0 to 360 degrees, so it is disconcerting to add two vectors representing distance and direction traveled and come up with an answer of "48 miles at a heading of -95 degrees". Sure, I can do the conversion in my head, but it's faster and easier to let the machine do it. It seems like such a simple and common thing that I'm surprised the 48 doesn't do it. Maybe this is a good idea for those rev F roms? :-) -- Roy Smith, Public Health Research Institute 455 First Avenue, New York, NY 10016 roy@alanine.phri.nyu.edu -OR- {att,cmcl2,rutgers,hombre}!phri!roy "Arcane?
