RAPPEL DERIVEE
f(x)=1/x alors f'(x)=-1/x^2
f(x)= sqrt(x) alors f'(x)= 1/2sqrt(x)

produit :
  u'*v+v'*u
  
somme:
  u'+v'
  
quotient:
  (u'*v-v'*u)/v^2
  
composée:
  g(x) de la forme ax+b
  f(x) la composée (une racine par exemple
  h(x) la fonction composée
  h'(x)= a*f'(ax+b)
  
Exemple :
  sqrt(2x-5)
  h'(x)=2*f'(2x-5)
  = 2*(1/2sqrt(2x-5))
  g(x)= 2x-5
  f(x)= racine de x
