Exemple de sortie écran :

  f : x-> cos(x)
 Df : x-> -sin(x)

  g : x-> cos(x) + 5
 Dg : x-> -sin(x)


  Compute the derivative of f and g with their definitions
  and the function fx_x();  when x = 0.500

  with   Df(0.500) = -0.47942554    
  with fx_x(0.500) = -0.47942554  

  with   Dg(0.500) = -0.47942554    
  with fx_x(0.500) = -0.47942554


  Remark : f(x) and f(x) + C have the same derivative
