# Math Help - find the regions where sinx< or = to x

1. ## find the regions where sinx< or = to x

i graphed it out and im just trying to understand if this would mean every pi sinx is less than x, I understand that it crosses through the x intercept every pi.

look at the graph ...

$\textcolor{blue}{\sin{x}} \le \textcolor{red}{x}$ for all $x \ge 0$

3. would sinx be equal to x at any point other than (0,0) or does it just come really close?

$x = \sin{x}$ at $x = 0$ only ... close to $x = 0$ , $x \approx \sin{x}$
