| Abstract: | Using fractional linear function ( also called pseudolinear function ) to approximate a function f ( x ) at a specific point Xo, a iteration scheme for the solution of equation f (x) = 0 is developed the variant of the method includes the well-known Hally method. Under the appropriate condition the quadratie convergence is proved. |
