Maxima has a variety of documented numerical solving routines.
If you're looking for Newton method, try
at the command line, which documents naive univariate
Newton-Raphson (newton) and multivariate Newton-Raphson ( mnewton). The
will show find_root, a combination of binary search and
Newton-Raphson which works for a larger variety of functions, realroots,
which uses Sturm sequences for univariate polynomials (real_root),
allroots for complex roots of polynomials. And so on.
Why doesn't solve use any of these methods? Because Maxima is
primarily a *symbolic* system, so solve looks for closed-form symbolic
Sorry, my mistake. I did a superficial search and it wasn't through
