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. $x<0$)

$$x<0\Longrightarrow |x|=-x\Longrightarrow\frac{-\sin|x|}{x}=\frac{\sin x}{x}\xrightarrow [x\to 0^-]{}1$$

    sorry for the dumb question but ... $$sin(-x) = -sin(x)$$ is it correct?2012-12-02

    Si, claro: el seno es una función impar....Yes, of course: sine is an odd function.2012-12-02
