Topic 10.2 False-Position Method (Examples). 2. False-position Method вЂў The bisection method divides the intervalx l to x u in half not accounting for the magnitudes of f(x l)and f(x u).For example if f(x l)is closer to zero than f(x u), then it is more likely that the root will be closer to f(x l)., False position method is a root-finding algorithm that is qualitative similar to the bisection method in that it uses nested intervals based on opposite signs at the endpoints to converge to a root, but is computationally based on the secant method. Unless otherwise specified, the function will be denoted . Initial exploratory phase.

The Regula Falsi (False Position) Method The Regula Falsi method is a combination of the secant method and bisection method. As in the bisection method, we have to start with two approximations aand bfor which f(a) and f(b) have di erent signs. As in the secant method, we follow the secant line to get a new approximation, which gives a formula Roots of Equations (Chapters 5 and 6) Problem: given f(x) = 0, п¬Ѓnd x. In general, f(x) can be any function.For some forms of f(x), analytical solutions are available. However, for other functions, we have to design some methods, or algorithms to п¬Ѓnd either exact,
