    Kenney, are you familiar with the TANGENT function? The domain and range of Tangent should help you figure this one out. Since it's the inverse function of tangent, it's domain and range will be reversed.

    or you can graph it and use the graph to see the domain and range

    -pi/2 <= x<= pi/ is the range?

    Hmmm yah that sounds right :) Since the range of tangent is all reals (due to those asymptotes, it makes the domain of arctangent all reals. And yah looks like you figured out the other one also c:
