Let,s suppose we wish to calculate the roots of a function f(x) [tex] f(x)=0 [/tex], of course you will say.."that,s very easy doc...just try Newton Method, fixed-point method or other iterative method"..the main "problem" we have is if f(x) includes non-differentiable functions such us the floor function [x] or the modulus of x |x| then how could we manage to solve it?..for example get the x values that satisfy [tex] g(x)-[g(x)]=0 [/tex](adsbygoogle = window.adsbygoogle || []).push({});

the problem is that [g(x)] is not differentiable for certain values of x....how could we solve that?... :yuck:
