Limit(3/n, n, oo, dir='-')
Detail solution
Let's take the limit
$$\lim_{n \to \infty}\left(\frac{3}{n}\right)$$
Let's divide numerator and denominator by n:
$$\lim_{n \to \infty}\left(\frac{3}{n}\right)$$ =
$$\lim_{n \to \infty}\left(\frac{3 \frac{1}{n}}{1}\right)$$
Do Replacement
$$u = \frac{1}{n}$$
then
$$\lim_{n \to \infty}\left(\frac{3 \frac{1}{n}}{1}\right) = \lim_{u \to 0^+}\left(3 u\right)$$
=
$$0 \cdot 3 = 0$$
The final answer:
$$\lim_{n \to \infty}\left(\frac{3}{n}\right) = 0$$
$$\lim_{n \to \infty}\left(\frac{3}{n}\right)$$

Lopital's rule
There is no sense to apply Lopital's rule to this function since there is no indeterminateness of 0/0 or oo/oo type
