Banach method

Remarks

Difficulties encountered in using Banach method, key pinpoints.

- Using python code to make a synthesis of the four basic methods of approximation.
- Using Geogebra and learning iteration scripting:
    - Iteration : ItérationListe((h(x(V), M), 0), V, {X}, k)
        - (h(x(V), M : point. x(V), the x coordinate of the variable V.
        - If different variables: V,W and initial values {V1,W1}, etc.
        - k is the number of iterations. Needn’t to enter in the function, it is just the repetition times, each next entry takes previous output.
    - Sequences, cursors, dependent objects.
- Correction reading of the exercise n°8:
    - As long as the interval is closed and any cord slope is bounded it is possible to calculate.
    - Draw attention in any interval of the function f is increasing,  if not take -f.
    - Conversion is possible.
