![]() Program 2.7: Root Search with the Newton method (appeared in the book). Program 2.6: Root Search with the bisection method (appeared in the book). C) If f(x L)*f(x M) = 0 then either f(x L) = 0 or f(x M). Your code should NOT include x U = x U.Īt each step for a) or b), we are shortening the interval by half its length, so that we eventually find the root. If so, USE THE SAME VALUE FOR x U (i.e., don't change x U), but reset x L to x M. 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. ![]() Here are the Bisection Method formulas xm = (xl+xu)/2 I'm not convinced that you understand what the above means.
