    Re: Haversine formula
    From: Henry Halboth
    Date: 2008 Apr 7, 20:02 -0700

    Hi Alex,
    
    I am not particlarly calculator literate, however, a
    realization that hav A = sin2 1/2A might be of help.
    Haversines do seem to have fallen into disuse, but
    most formulae employing them an be converted to the
    use of sines.
    
    Regards,
    
    Henry
