Using while do loop is a bad idea, as it can easily get
into infinite loop. It would be better if the solver "give-up"
if it cannot converge within some maximum iterations.
Another problem is the df function.
A symbolic df function may be hard to get (or messy)
Even the f function may be hard to get.
Most engineering problem involve simultaneous system of
equations, which were hard to simplify into a single f
It is much easier using, say TK solver, instead of Lua.
Instead of a bunch of equations for solving different variable,
Just leave the input field(s) blank (or guess values), and type !
Excel spreadsheet solver is another option.
