The bisection method finds a root of f(x).[br]0. Enter a function f(x). For example, x*sin(x^2)[br]1. Bracket the root in the interval [a,b]. Change the input values for a and b so that f(a)*f(b) < 0.[br]2. Click "Step" button to find the next bracket.[br]"Reset" button sets back to initial interval.
