As I derived a generalization for a 3D parameterized curve yesterday, I'd
noticed a mistake in my equation posted below, a factor '2' in expression
involving x'[t]^2, should be '1'.
Since this forum is of an alt. type, I've published the whole notebook at

Bye,
Borut
p.s. A 'fillthegap' riddle for those interested in physics lore. Richard
Feynman once said:
"Science is like _ _ _, sometimes something useful comes out, but that is
not the reason why we are doing it."

 1) I'll leave rederiving equation to you, here is what I've got (just
copy
 paste it).:

 \!\(getEq[
 f_] := \[IndentingNewLine]\(x''\)[
 t] + \(x'\)[t]\^2\ \(2\ \(f'\)[x[t]]\ \(f''\)[x[t]]\)\/\(1 +
 \(f'\
 \)[x[t]]\^2\) + \(g\ \(f'\)[x[t]]\)\/\(1 + \(f'\)[x[t]]\^2\) == 0 /. g >
 1\)
