p) limita = 0/0 Aplici teorema lui L Hospital
L=lim(sin 4x) `/(sin 3x) `=4cos4x/3sin3x=4/3 x→0
___________________
q.limita e 0/0 Aplici teore,a L Hospital x→0
L=lim (sin2x+sin3x) `/(sin4x) `=lim(2cos2x+3cos3x)/4*cos4x= (2+3)/4=5/4
r)limita e 1^∞ Prelucrezi expresia de la limita
Ridici paranteza concomitent la puterea 2x si 1/2x pt ca expresia sa ramana neschi,bata.Obtii
lim [(1+1/2x)^2x]^x/2x
Paranteza dreapta este numarul e. Limita devine
e^lim x/2x=e^1/2=√e
