Just looked up the Lambert W Function (which I'd not heard of before)
in Wikipedia. It sounds like the solution to tanh z = 1/z might be
expressible in terms of it.
I got the numerical solution by starting with 1 and pushing the tanh
and 1/x keys alternately until the result (after 1/x) converged.
This method doesn't always work (and is not the most efficient when
it does), but it's so simple it's worth trying as a starter.

Why not use the Lambert W function?Â It's included in the WP-34s!Â Â
Just solveÂ z = 1/(asinh(1/z)+W(1/ln(z)) for n.
