Figure 1 f x x3 2x2 3x 1 1 Note f 0 f 2 2 2 4 0 so f indeed has a root in 0 2 by IVT Set p 1 1 and notice f 0 f 1 2 1 0 so choose a 2 b 2 1 2 2 Set p 2 1 2 2 3 2 and notice f a 2 f p 2 1 9 4 2 1 4 0 so choose a 3 b 3 1 3 2 3 Set p 3 1 3 2 2 5 4 Example 1 Consider finding the root of f x x2 3 Let step 0 01 abs 0 01 and start with the interval 1 2 Table 1 Bisection method applied to f x x2 3 Thus with the seventh iteration we note that the final interval 1 7266 1 7344 has a width less than 0 01 and f 1 7344 0 01 and therefore we chose b 1
The value of x3 x 3 is then chosen as either the midpoint of x0 x 0 and x2 x 2 or as the midpoint of x2 x 2 and x1 x 1 depending on whether x0 x 0 and x2 x 2 bracket the root or x2 x 2 and x1 x 1 bracket the root The root therefore stays bracketed at Approximate the root of f x x 3 3 with the bisection method starting with the interval 1 2 and use step 0 1 and abs 0 1 Answer 1 4375 Question 2 Approximate the root of f x x 2 10 with the bisection method starting with the interval 3 4 and use step 0 1 and abs 0 1

x 3 x 2 1 0 by bisection method - In mathematics the bisection method is a root finding method that applies to any continuous function for which one knows two values with opposite signs The method consists of repeatedly bisecting the interval defined by these values and then selecting the subinterval in which the function changes sign and therefore must contain a root
