Would someone please explain the math above? I don't get the missing steps. For instance: tan(l)=Asin(m-m0) What is l, m and m0? l is the latitude and m is the longitude.

Re: BR Maths Corner-1

As I'd suspected, found out that it's trivial working in spherical coordinates: Equation of a great circle is: tan(l)=Asin(m-m0) Use the latitude, longitude values for A and V and solve to get A=-3.948 and m0=-36.71 deg. This is equation of the great circle connecting A and V. We need to find the lo...

Re: BR Maths Corner-1

I used the north star longitude on the ecliptic system - 90 E and the plot now matches yours nicely. The times when the A and V longitudes match up are 13400 BC - 4500 BC.
