Evaluating Inverse Trig Expressions

You are given an inverse trig function to evaluate at a particular special value. Imagine what the full graph of the inverse trig function would look like and then visualize the point on the graph that corresponds to the given input and think about what the output would be. Click the "Show Graph" button to see if you've visualized correctly and then the "Show Value" button to confirm that you've evaluated the expression correctly.
