Method of False position (Or) Regula-Falsi method (Or) Linear interpolation method

In bisection method the interval is always divided into half. If a function changes sign over an interval, the function value at the midpoint is evaluated. In bisection method the interval from a to b into equal intervals ,no account are taken of the magnitude of .An alternative method that exploits this graphical insights is to join by a straight line.

The intersection of this line with the X-axis represents an improved estimates of the root.The replacement of the curve by a straight line gives a “false position” of the root is the origin of the name ,method of false position ,or in Latin ,Regula false .It is also called the linear interpolation method.
