We consider bisection method for finding the root of the function f(x) = 2.3 – 1 on the interval [0, 1], so Xo = 0.5. We perform 2 steps, and our approximations Xi and X2 from these two steps are: O x1 = 1, X2 = 0.6 O x1 = 0.7, x2 = 0.8 O x1 = 0.75, x2 = 0.875 O x1 = 0.3, 22 = 0.6

Suppose you wish to find the root r of a function f(x), that is,
the value r where f(r)=0. One method is to make an initial guess,
x0, compute the line tangent to f at x0, and find where the tangent
line intercepts the x-axis, x1. Then, use x1 as the second guess
and repeat this procedure n times until f(xn) approximately equals
0 and report xn as...

Q2 2015
a) show that the function f(x) = pi/2-x-sin(x)
has at least one root x* in the interval [0,pi/2]
b)in a fixed-point formulation of the root-finding problem, the
equation f(x) = 0 is rewritten in the equivalent form x = g(x).
thus the root x* satisfies the equation x* = g(x*), and then the
numerical iteration scheme takes the form x(n+1) = g(x(n))
prove that the iterations converge to the root, provided that

In class, we have studied the bisection method for finding a root of an equation. Another method for finding a root, Newton's method, usually converges to a solution even faster than the bisection method, if it converges at all. Newton's method starts with an initial guess for a root, xo, and then generates successive approximate roots X1, X2, .... Xj, Xj+1, .... using the iterative formula: f(x;) X;+1 = x; - f'(x;) Where...
