WitrynaGraphical Methods: A simple method for obtaining an estimate of the root of the equation f(x)=0 is to make a plot of the function and observe where it crosses the x axis. This point, which represents the x value for which f(x) = 0, provides a rough approximation of the root.

Witryna5 cze 2012 · The solution x of a nonlinear equation f (x) = 0 is termed a root of the equation or a zero of the function f (x). Application of numerical techniques to obtain the roots of nonlinear equations is the focus of this chapter. Nonlinear equations that are not amenable to an analytical solution may be solved using iterative numerical schemes. WitrynaAmong various numerical methods for locating roots, Bisection method is one of the simplest methods for implementing on computer. Bisection method is a bracketing method which relies on two initial guesses to bracket the root. The method capitalises the fact that the function changes sign on opposite sides of the root.
