Help with Latitude and Longitude.

I have a list of cities w/ latitude and longitude that I have to find the
distance between any two of the cities. The formula I was given is this.....
69*(difference in latitudes)2 + (difference in longitudes)2
VLOOKUP is used for the differences and needs True or False.
Ofcourse I have just started excel so this is really aggrivating.

Considering that Earth is round I would have thought some trig enters into
the calc.
Check Chip Pearson's page for his method.
