Question

rezolvare cat mai urgenta ​

Answer 1

Răspuns:

Explicație pas cu pas:

lim/x-->1 x^3 -- 1 / x^2 -1 =

lim/x-->1 (x^3 -- 1)´ / (x^2 -1)´ =

lim/x-->1 3x^2 / 2x = 3/2 = 1 1/2.

Answer 2

$\it \lim\limits_{x \to 1} \dfrac{x^3-1}{x^2-1}=\lim\limits_{x \to 1} \dfrac{(x^3-1)'}{(x^2-1)'}=\lim\limits_{x \to 1} \dfrac{3x^2}{2x}=\dfrac{3}{2}=1\dfrac{1}{2}$
