Abstract
A two-sided method for finding a zero of 'a real-valued function on a given interval is presented and its convergence features are analysed, This method combines ih a simple way the well known schemes of Newton Raphson and Regula Falsi to produce two sequences of approximations to the root of the equation. For simple roots this convergence turns out to be of third order, and under more restrictive conditions it is also monotonic. Though oriented toward interval methods, no use of interval arith ...

For simple roots this convergence turns out to be of third order, and under more restrictive conditions it is also monotonic. Though oriented toward interval methods, no use of interval arithmetic is made. ...
