in this page they are descrbing the forthmentioned technique.(adsbygoogle = window.adsbygoogle || []).push({});

and im quite puzzled, because if i get this interval:

[1,2]

let's take the equation f(x)=x^2.

now if we follow the algorithm we find that there might not be a root between them, which is ofcourse absurd. (sqrt2 and sqrt3 are ofcourse included inbetween).

anyway, here is the page http://spiff.rit.edu/classes/phys317/lectures/closed_root/closed_root.html
