 lim |-|

limx0+(yx)\lim_{x \to 0^+}\left(\frac{y}{x}\right)
Limit(y/x, x, 0)
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
Other limits x→0, -oo, +oo, 1
limx0(yx)=sign(y)\lim_{x \to 0^-}\left(\frac{y}{x}\right) = \infty \operatorname{sign}{\left(y \right)}
More at x→0 from the left
limx0+(yx)=sign(y)\lim_{x \to 0^+}\left(\frac{y}{x}\right) = \infty \operatorname{sign}{\left(y \right)}
limx(yx)=0\lim_{x \to \infty}\left(\frac{y}{x}\right) = 0
More at x→oo
limx1(yx)=y\lim_{x \to 1^-}\left(\frac{y}{x}\right) = y
More at x→1 from the left
limx1+(yx)=y\lim_{x \to 1^+}\left(\frac{y}{x}\right) = y
More at x→1 from the right
limx(yx)=0\lim_{x \to -\infty}\left(\frac{y}{x}\right) = 0
More at x→-oo
