Use the bissection method to approximate the root of f(x)=2x^2-1 in the interval (0,1). Let ε =0.1be the margin of error of approximation.0.1be the margin of error of approximation.
The initial interval is "(0,1)" and "f(0)=-1, f(1)=1" .
Step 1: "m=(0+1)\/2=0.5" and "f(m)=f(0.5)=-0.5." New interval is "(0.5,1)"
Step 2: "m=(0.5+1)\/2=0.75" and "f(m)=f(0.75)=0.125" New interval is "(0.5,0.75)"
Step 3: "m=(0.5+0.75)\/2=0.625" and "f(m)=f(0.625)=-0.21875" New interval is "(0.625,0.75)"
Step 4: "m=(0.625+0.75)\/2=0.6875" and "f(m)=f(0.6875)=-0.0546875" New interval is "(0.6875,0.75)"
Since "0.75-0.6875=0.0625<0.1"
which is the margin of error, we can stop the approximation.
The root is in the interval "(0.6875,0.75)" .
