  1. V\u00e9rifier que si on choisit $a=5$ et $n=3$, le r\u00e9sultat affich\u00e9 est $125$.<\/li>\n
  2. Qu’affiche ce programme quand on choisit $a=2$ et $n=5$ ?<\/li>\n
  3. Exprimer $res$ en fonction de $a$ et de $n$.<\/li>\n
  4. Que fait ce programme ?<\/li>\n<\/ol>\n

    Exemple 2<\/h2>\n
    \n
    \/*------------------------------\nVariables\nn : entier\nk : entier\nres : reel\n\/*------------------------------\nSaisir n\nres:=1\nPour k de 1 jusqu'a n\n    res:=res*k\nAfficher res\n\/*------------------------------<\/pre>\n

    1. V\u00e9rifier que si on choisit $n=3$, le r\u00e9sultat affich\u00e9 est $6$.<\/li>\n
    2. Qu’affiche ce programme quand on choisit $n=5$ ?<\/li>\n<\/ol>\n
      NB : Ce programme calcule $factoriel(n)$ souvent not\u00e9 $n!$<\/p>\n

      Exemple 3<\/h2>\n
      \n
      \/*------------------------------\nVariables\na : reel\nn : entier\nk : entier\nres : reel\n\/*------------------------------\na:=5\nSaisir n\nPour k de 1 jusqu'a n\n    a:=2*a+3\nAfficher res\n\/*------------------------------<\/pre>\n

      2. Qu’affiche ce programme quand on choisit $n=4$ ?<\/li>\n
      3. Derri\u00e8re ce programme se cache une suite $(u_n)$. D\u00e9finir cette suite par son premier terme $u_0$ et par sa relation de r\u00e9currence.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
