The Secant Method One drawback of Newton’s method is that it is necessary to evaluate f0(x) at various points, which may not be practical for some choices of f. The secant method avoids this issue by using a nite di erence to approximate the derivative. As a result, f(x) is approximated by a secant line through

It is clear from the numerical results that the secant method requires more iterates than the Newton method (e.g., with Newton’s method, the iterate x 6 is accurate to the machine precision of around 16 decimal digits). But note that the secant method does not require a knowledge of f0(x), whereas Newton’s method requires both f(x) and f0(x).

we produce a linear function q(x) = a0 + a1x with q(x0) = f (x0), q(x1) = f (x1). (*). This line is sometimes called a secant line. Its equation is given by.

May 28, 2021 · derivation of secant method. It can be noted that x i and x i+1 are two initial guesses. Since it is an open bracketing method so it is not necessary to bound the root of the original equation within the selected interval. The interval is updated using the most recent points. As will be shown in the example below.

The secant method is defined by the recurrence relationAs can be seen from the recurrence relation, the secant method requires two initial values, x0 and x1, which should ideally be chosen to lie close to the root.
