  1. In the graph, the red curve is a portion of y = sin(x), trace over the curve, thinking of the ordered pairs that make up this graph.
  2. The blue curve is the inverse of y = sin(x), trace over the curve, see that each ordered pair is the reverse of a corresponding point on the y = sin(x) curve.
  3. What line of symmetry lies between the two curves?
  4. See the "Hands-On Activities" section for Inverse Sine, Cosine and Tangent applets.
