Use a graphing calculator to graph Y?, Y2, and Y? +Y? on the same screen. Evaluate each of the three functions at X=?/6 and verify the following equality Y?(?/6) +Y?(?/6)=(y?+Y?) (?/6)Y?=tanX, y?=sec2xa)Y?(?/6)= b)Use the graphing functions of your calculator to evaluate Y? at (?/6)c)Use the graphing functions of your calculator to evaluate Y?+Y? at(?/6)
