Use a graph of sine or cosine to estimate each value. Graph f(x) = Sin-1 a and g(x) = Cos-1x. (Hint: Use what you learned about graphs of inverse functions in Lesson 9-5 and inverse trigonometric functions in Lesson 13-4.) On the same set of coordinate axes, graph f(theta) and g(theta). What are the approximate coordinates of the points of intersection of f(theta) and g(theta)? When isf(theta) > g(theta)?
