Numerical Methods

Solve an equation by bisection, Newton’s method or false position with a table of steps.

Method:

Bisection

Newton’s method

False position

f(x) =

a =b =tolerance ε =

The equation f(x) = 0. For bisection and false position f must have different signs at the ends.

This calculator solves f(x) = 0 by bisection, Newton’s method or false position and shows a table of steps.

Bisection is reliable but slow: it needs an interval with different signs at the ends.
Newton’s method is fast but may fail from a poor starting value.
False position uses the same interval and usually converges faster than bisection.
