Algorithm for Bisection Method

1.Decide the initial values forx1 and x2 and stopping criterion,
E.
2.Compute f1 =f(x1) and f2 = f(x2)
3.If f1*f2>0, then x1+x2 do not bracket any root and goto
step7. otherwise continue.
4. Compute xm = (x1+x2)/2 and compute f0=f(x0).
5. If f1*f0<0 then
 set x2=xm
 else
 set x1=xm
6. If absolute value of (x2-x1)/x2 is less then error E, than
 root = (x1+x2)/2
 write the value of root,
 goto step 7
 else,
 goto step 4
7. stop.
