I find the following formula from an old Texas pgr for TI 59
havD =hav(Ls-Ld)cos(ls).cos(ld)+hav(ls-ld)
For your info, ls,ld are the starting and destination latitudes,
while Ls and Ld are the starting and destination longitudes
D is the great circle distance
I want to write that in basic but what the hell this "hav" can mean?
Can somebody explains? Thanks in advance.
OLD Texas Pgm
wow, a TI-59? NICE!
I only know TI BASIC for the 8X series, but most of the people here only know Qbasic or similar.
havD is probably a special variable that when changes, you get some special output. like on a graphing calc, you can change variables that affect the graph output.
I dont really know anything about it though...

hav mistery
Thanks for answer. I thought the meaning was something like absolute value but apparently no. h for hemispherical? no something about graph y'are right.

Try hexadecimal value: &HD in Qbasic
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15
1 thru 9 are normal decimal values based on 0 thru 15 or 16 digits.
