comment Expected value of minimum distance
@tohecz, hmm.. good point. I'm not sure, but for now I think mean value of $x$ (as a function of $m$ and $n$) will be enough.

comment What numerical methods can solve $\sin(x) + \sin(y) = \sin(xy)$
it seems that this method is somehow similar to the second method suggested by Robert Israel. thanks for your answer, it gives some perspective from analytical viewpoint.

@lhf, great links! (definitely I need to understand interval arithmetic)

@J. M.: thanks, it seems quite useful (but first I need to read hundred of pages to understand interval arithmetic). I wish I could accept your answer.

sorry, but I don't see how this answers my question. As I understand you are trying to represent original equation in parametric form by comparing two Taylor expansions. But wolframalpha draws something completely different for resulting equation.

comment Do objects in category form a set?
btw, it's possible to define categories without notion of object, with arrows only

thanks! can you give some references to more detailed description of these methods, or maybe their names (which I can google for)?

@user3196, nice! But to draw a graph I need many solutions. How can I find them? By choosing different starting points?
