1. An acute angle 6' is drawn in the unit circle diagram. Identify the lengths below. 0132 OT: PT= OS: 2. Using the figure in problem 1, suppose 6 = 35". Find the area of the triangle with vertices 0, P, 5. Calculate this area using two different methods. 3. a) Let x be the length of PT. Find a function that gives 6 in terms of x. b) Based on the figure, what happens to 6 as x goes to infinity? c) Sketch a graph of the function you found in part a) where 9 is on the vertical axis and x is on the horizontal axis
