degrees, radians, vector?

[tlclear]

I have lat/longs. what i need to find is the direction from one lat/long to another. would prefer direction to be from 0 thru 360 degrees, but probably can work with some other measure. any help will be appreciated.

thanks

Gee, been so long since I worked with Radians, etc that it'd feel like working it out all over again.

I typed the keyword Radians into the VBA help and came up with a list of functions. ATN, SIN, TAN, COS, Circle. It appears the key items to work out vectors/Radians/degrees are in fact present within Visual Basic. What it's going to come down to is your ability to write a program that performs the calculations.

It's very easy to perform mathematical manipulations on numbers - reading values out of tables. What I can't do at the moment is give you the math to do it. If you could present a formula, I'm sure somebody can whip out a demo method in a few minutes.
