Steps to find the zero point of a function by dichotomy:

1. Determine the interval where the zero point of the function is located (using the above theorem)

2. Find c=(a+b)/2.

3. Judge whether f(c)=0 is true, if so, c is the zero point of the function, if not, proceed to the next step.

4. Judge F (a) F (c)

5. Judges | A-B |
