Application of the MVT
Finite Variations Inequalities
  | f ’(x)| ≤ M  =>| f(b) – f(a) | ≤  M |b - a|.

Application to the study of convergence
of some Recursive Sequences :
un+1 = f(un ) f(a) = a (fixed point)
| f ’(x)| ≤ k      (0 < k < 1)
|un+1a |=|f(un) – f(a)| ≤ k.| un - a |

|un - a | ≤ kn.| u0 - a |

Lim un = a


un+1 = Cos un

coss(un)

k = √3 / 2

un+1 = f(un )
