5. If a = 0.1 and b=1.0, how many steps of the bisection method are needed to determine
the root with an error of at most 0.5×10¯8 ?
6. If the bisection method is used starting with the interval [1, 3], how many steps must be
taken to compute a root accurate to 4 decimal places?
7. Consider the bisection method starting with the interval [1.0. 2.5]. Find the width of the
interval at the n-th step of this method. What is the maximum distance possible between the
root and the midpoint of this interval?
