Un truc comme cela
integer{a=randint(-10..-1)*randint(1..10)}
integer{b=randint(1..10)}
integer{c=randint(-10..10)}
function{tg=frac{1}{k},frac{1}{k^2},frac{k}{k+1},k,k^2,k^3,a*k+b,a*k,sqrt(k),(a*k+b)^2}
integer{i=randint(1..10)}
text{reponses=demander n, u prend la valeur 0, tant que k (leq) n,
u prend la valeur u+evalue(tg,k),k prend la valeur k+1,
fin tant que,afficher u}
statement{
<p>
On considère la suite ((u_{n})) définie, pour tout entier n>0, par
(displaystyle{u_{n}=sum_{k=1}^{n}tgtext}). Ecrire un algorithme permettant de calculer
le terme (u_n)
