PAL Worksheet 21 1. Suppose that the terminal side of an angle φ lies in the second quadrant. In what quadrant do each of the following lie? π c. −φ d. φ − 3π a. φ + π b. φ + 2 e. φ − 3π 2 f. −φ + π g. π −φ 2 h. − 3π −φ 2 5π 2. The terminal side of the angle intersects the unit circle at the point (−0.623, 0.782), approx7 imately. 5π intersect the unit a. Where does the terminal side of the angle − 7 circle? 2π b. Where does the terminal side of the angle − intersect the unit 7 circle? c. Find an angle whose terminal side intersects the unit circle at the point (0.623, 0.782). d. Find an angle whose terminal side intersects the unit circle at the point (−0.623, −0.782). e. Find an angle whose terminal side intersects the unit circle at the point (0.623, −0.782). √ 5 and sin α = 3. If cos α = 6 a. cos(−α) b. sin(−α) c. cos(α + π) d. sin(α + π) e. cos(π − α) f. cos(α − π) π g. cos α − 2 π h. sin α − 2 √ 31 , use a picture of the unit circle to find each of the following: 6
