How could you find the distance between two points, such as
N12° 34.567 W12° 34.567 and N12° 34.568 W12° 34.567?

Guys, I wanted to know how I could get the answer, not for you to tell me or give me an app to do do it for me.

Use a great circle. The equation is given here:

"Unfortunately, the flattening of the Earth cannot be taken into account in this simple derivation, since the problem is considerably more complicated for a spheroid or ellipsoid (each of which has a radius which is a function of latitude). This leads to extremely complicated expressions for oblate spheroid geodesics and geodesics on other ellipsoids."
So you won't get the most accurate solutions; but that's no problem if dealing with relatively short distances.
