Root-Finding Problems

f(x)=0\begin{aligned} f(x) = 0 \end{aligned}

Bisection Method

Regula Falsi (False Position)

Newton's Method

Order of Convergence

Let rr be the root of our function and xnx_{n} be the nn-th approximation ot the root. Then we define the error as

ϵn=rxn. \begin{equation} \epsilon_{n} = r - x_{n}. \end{equation}

For large nn we assume the approximate relatonship

ϵn+1=kϵnp \begin{equation} |\epsilon_{n+1}| = k |\epsilon_{n}|^{p} \end{equation}
