There is a formula that converts eccentric anomaly to true anomaly and vice versa:


I just noticed that \[\sqrt{\frac{1+e}{1-e}}=\exp(\tanh^{-1}(e))\] which could save some keystrokes (or precious program steps) on a calculator which has atanh function.

Also this is a rare opportunity to use that built in function that almost nobody ever uses.

Nice shortcut,

But I thought marriage did that!

Geoff; She probably always qualified, but I think that marriage granted your wife sainthood.
