Halley's method - Wikipedia
https://en.wikipedia.org/wiki/Halley's_method In numerical analysis, Halley's method is a root-finding algorithm used for functions of one real variable with a continuous second derivative. It is named after its inventor Edmond Halley. The algorithm is second in the class of Householder's methods, after Newton's method. Like the latter, it iteratively produces a sequence of approximations to the root; their rate of convergence to the root is cubic. Multidimensional versions of this method exist.

As in Halley's irrational formula, take the second-order Taylor series (1) A root of satisfies , so (2) Now write (3) giving (4) Using the result from Newton's method , (5) gives (6) so the iteration function is (7)
Halley's method - Wikipedia
en.wikipedia.org › wiki › Halley&Method Edmond Halley was an English mathematician who introduced the method now called by his name. Halley's method is a numerical algorithm for solving the nonlinear equation f ( x) = 0. In this case, the function f has to be a function of one real variable. The method consists of a sequence of iterations: beginning with an initial guess x0.
