I would like to know how the fsolve function finds the solution. Is it a method like Newton's method?

fsolve dosn't exist in Sage.

Do you mean find_root ?
Do you use an optional package ?

I suppose you're talking about scipy.optimize.fsolve, which is itself a wrapper for scipy.optimize.root. Iss documentation lists (but does-not describe) the various available methods, the default being hybr, which

uses a modification of the Powell hybrid method as implemented in MINPACK [1].

I won't paraphrase the related Wikipedia entry, but point out this previous question, which might be useful...

HTH,
