# Find left limit $\lim\limits_{x \to{}0}{\frac{-\sin|x|}{x}}$

I have a little confusion with signs. Thanks in advance.

$$\lim_{x \to 0^-}{\frac{-\sin|x|}{x}}$$ (This is a left limit, i.e. $x<0$)

What is $sen{}$? – Chris Eagle Dec 2 '12 at 16:51
@ChrisEagle It's $\sin$ in spanish (seno). – Pragabhava Dec 2 '12 at 16:52
It's already edited, thanks for a while. – Rakisbro Dec 2 '12 at 16:53
Do you mean $\lim_{x\to 0^-}$ when you say left limit? – Asaf Karagila Dec 2 '12 at 16:54
that's that I mean Asaf. – Rakisbro Dec 2 '12 at 17:00

$$x<0\Longrightarrow |x|=-x\Longrightarrow\frac{-\sin|x|}{x}=\frac{\sin x}{x}\xrightarrow [x\to 0^-]{}1$$
sorry for the dumb question but ... $$sin(-x) = -sin(x)$$ is it correct? – Rakisbro Dec 2 '12 at 17:04
