Dérivée d'un quotient

On donne la fonction f définie sur RR par   f(x)=2xx 2+2.

Nous allons calculer f(x) par étapes.

  • On peut écrire f comme un quotient uv, où les fonctions u et v sont définies sur RR par :
    u(x) =   et   v(x)=
  • Les fonctions u et v sont dérivables sur RR :
    u(x) =   et   v(x)=
