fortran program for secant method numerical analysis

The root should be correct to three decimal places. Emphasizing the finite difference approach for solving differential equations, the second edition of Numerical Methods for Engineers and Scientists presents a methodology for systematically constructing individual computer programs. Since, x 2 and x 3 matching up to three decimal places, the required root is 1. Providing easy access to accurate solutions to complex scientific and. Numerical Methods for Engineers and Scientists, Second Edition. Secant Method Example Secant Method On Youtube for: obsolete, secant method, function zeros title: Rootfinder.

for: transportable Fortran programs for management and exchange of programs and other. Here are the Bisection Method formulas xm = (xl+xu)/2 I'm not convinced that you understand what the above means. X L - Lower (left) endpoint of an interval x M - Midpoint of an interval x U - Upper (right) endpoint of an interval a) If f(x L).f(x M) 0, the graph of the function does not cross the x-axis between x L and x M, so we should look in the other half of the interval - in x M, x U.

If so, USE THE SAME VALUE FOR x U (i.e., don't change x U), but reset x L to x M. At each step for a) or b), we are shortening the interval by half its length, so that we eventually find the root. C) If f(x L).f(x M) = 0 then either f(x L) = 0 or f(x M).
