Did you spot the error in my math, deliberately made to test you? :)
No? Well Steve did. Hard to believe I actually used a calculator and
STILL got that multiplication wrong. Thanks, Steve!
The correct calculations are:
MCD = 2 * 6371 * arccos [ 6371 / (6371 + 1460) ]
= 12742 * arccos [ 6371 / 7831 ]
= 12742 * arccos [ 0.8135614864 ]
= 12742 * 0.620545318575
= 7,906.98 Km (4913.16 miles)
