SOMME 
L+L' = L+L'
L + +inf = +inf
L + -inf = -inf
+inf + +inf = +inf
-inf + -inf = -inf
+inf + -inf = FI

PRODUIT
L*L' = L*L'
L * +inf = +inf
L * -inf = -inf
+-inf * +-inf = regles signe
0 * +-inf = FI

QUOTIENT
L/L' = L/L'
+-inf/L = regles signe
L/+-inf = 0
L ou -+inf/0 0+ 0- = regles signe
0/0 = FI
+-inf/+-inf = FI

en +inf e**x/x**n=+inf
en +inf lnx/x**n=0
en -inf x**n * e**x =0
en -inf e**x/x**n=0
en 0+ x**nlnx=0
en 0+ lnx/x =-inf

Convergence d'une suite
Un<Un+1 -> Un croissante
Un<C -> Un majoree par C

Un>Un+1 -> Un decroissante
Un>C -> Un minoree par C

Si q<=1 alors lim q^n existe pas
Si -1<q<1 alors lim q^n = 0
Si q>1 alors lim q^n = +inf
