Computing a limit graphically and analytically

a. Graph  with a graphing utility. Comment on any inaccuracies in the graph and then sketch an accurate graph of the function.

b. Estimate  using the graph in part (a).

c. Verify your answer to part (b) by finding the value of  analytically using the trigonometric identity sin 2θ = 2 sin θ cos θ.
