BISECTION ERROR BOUND
Theorem 21 Suppose that fe Cla, b) and f(a) f(b) <0. The Bisection method generates a sequence
(n.) approximating a zero p off with
b-a
IP-Pl≤2· when #21.
The above error bound is often used to find the number n of iterations required to achieve some desired error IP-pl.n 21.
In many cases, we have a desired error bound that we had like to achieve. Say we want the error IP-pl= 10, where k is
known. Then we can find a bound on n from the inequality
