WebThe bisection method uses the intermediate value theorem iteratively to find roots. Let f ( x) be a continuous function, and a and b be real scalar values such that a < b. Assume, without loss of generality, that f ( a) > 0 and f ( b) < 0. Then by the intermediate value theorem, there must be a root on the open interval ( a, b). Webrequires two function evaluations per iteration, that of f(x n) and f0(x n). The secant method x n+1 = x n f(x n) x n x n 1 f(x n) f(x n 1); n = 1;2;3;::: requires one function evaluation per iteration, following the initial step. For this reason, the secant method is often faster in time, even though more iterates are needed with it than with ...
