    Sketching A Graph

    Hey guys, how would I sketch a graph of y = arccos(cos x) for all values of x? I begin defining the domain and range for cosx, but where do I go from there?

    For values in the domain: \arccos(\cos(x)) = x

    Oh ok. Just doubling checking, but would there be any restrictions to the domain and range of this graph?

    y = \arccos(\cos{x})

    -1 \le \cos{x} \le 1

    domain ... x \in \mathbb{R}

    range ... 0 \le y \le \pi
