The Newton-Raphson method is a numerical method to solve equations of the form f(x) = 0.

This method requires us to also know the first differential of the function. But the Newton-Raphson method has very good convergence, so it can often provide an accurate result very quickly.

Example — square root of two using Newton-Raphson…
