Investigation 8: Inverse Trigonometric Functions

Step C

• Note: Unless the window settings are set up on the calculator properly before you follow the sequence of steps outlined in the Investigation, you will not be able to see the graph.
• Recall: The graphs of inverse functions are reflections in the line y = x.
• Recall the Vertical Line Test: If the graph of an equation is such that no vertical line intersects the graph in more than one point, then the graph represents a function.
