Please, I need clarification on this queston
Show that the equation
0 = x/2 -1/x
,x>0, has a root in the interval [1, 2].
b Obtain the root, using interval bisection two times. Give your answer to two significant figures.
I am actually wondering how many times do I find (a+b)/2. The question obviously states twice. But the answer was based on 4 interval bisections! I obtained 1.3 and they obtained 1.4. Can anyone please comment?
