Halley's Method is a method of solving an equation $\map f x = 0$ involving the real function $f$ for which there may be no convenient closed form solution.
The derivative and the second derivative of $f$ have to be known in order to use Halley's Method.
Let $x_0$ be an initial guess.
Halley's Method uses the iteration:
- $x_{n + 1} = x_n - \dfrac {\map f {x_n} } {\map {f'} {x_n} - \dfrac {\map f {x_n} \map {f} {x_n} } {2 \map {f'} {x_n} } }$
where:
- $\map {f'} {x_n}$ is the derivative of $f$ with respect to $x$ evaluated at $x_n$
- $\map {f} {x_n}$ is the second derivative of $f$ with respect to $x$ evaluated at $x_n$.
