SECTON : A COMBINATION OF NEWTON METHOD AND SECANT METHOD FOR SOLVING NON LINEAR EQUATIONS

Newton method is a famous method for solving non linear equations. However, this method has a limitation because it requires the derivative of the function to be solved. Secant method is more flexible. It uses an approximation value to the derivative value of the function to solved. Unfortunately, this method needs two initial values, compared to Newton method which only need one initial value. The use of numerical technique gives an approximation value of the solution. An initial value should be iterated until it approximates the solution. This means, the numerical solutions always contain error ( ). In this paper, the initial point of Newton method and are used to make the second initial value of the Secant method. Secton method is constructed by applying these initial values to the Secant method. The experiments show that Secton method only gives a small deviation, compared to Newton method
