Finding solutions for functions f(x)=0, like f(x)=x5-3x-1=0.

This page tries to find solutions for any function f(x). You can use cos, sin, pow, PI, like in these equations : Enter your own function, interval and press "search" button.
Note: only solutions x for sign(f(x-ε))!=sign(f(x+ε)) are given, i.e. solutions for f(x)=cos(x)*cos(x) won't be found because f(x)>=0.

f(x)= for x=[, ]
Compute f(x) for x=
