- 1. 1<br />MULLER METHOD<br />Jeannie Castaño 2053298<br />
- 2. This is a method to find the roots of equations polynomials in the general way: <br /> Where n is the order of the polynomial and they are they constant coefficients. Continuing with the polynomials, these they fulfill the following rules: <br />" For the order equation n, is n real or complex roots. It should be noticed that those roots are not necessarily different. <br />" If n is odd, there is a real root at least. <br />" If the complex roots exist, a conjugated couple exists.<br />
- 3. DEFINITION<br />It is the method secant, which obtains roots, estimating a projection of a direct line in the axis x, through two values of the function.<br />The method consists on obtaining the coefficients of the three points, to substitute them in the quadratic formula and to obtain the point where the parable intercepts the axis x. <br />

- 6. The last equation generates that , this way, one can have a system of two equations with two incognito:<br />Defining this way: <br />Substituting in the system: <br />
- 7. Having the coefficients as a result: <br />Finding the root, you to implement the conventional solution, but due to the error of rounding potential, an alternative formulation will be used:<br />Error<br />
