NAME: SECTION: Instructor: TO RECEIVE CREDIT FOR AN ANSWER, YOU MUST SHOW WORK JUSTIFYING THAT ANSWER. I. (NC CALCULATOR) (30 points) Give the EXACT values of: cos 6, sin 0, tanQ and the length of the line segment OH. Give the exact value of the angle a in degrees and in radians. Give the exact values of the area of the shaded region, and of the length of the arc of circle from C to C". The circle, whose arc is shown of the ﬁgure, has its center at 0. II. (NO CALCULATOR) (30 points) On the ﬁgure, show the possible terminal sides for an angle 9 in standard position, such that cos 0 = —%. For each of these terminal sides, give the corresponding values of sin0 and tan 6. Keep exact values. \( III. (30 points) Evaluate the length h.
