Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. 001 (part 1 oF 4) 10.0 points a) Without using a calculator, fnd two values oF θ that satisFy the condition cos θ = 2 2 . 1. 0 , 180 2. 60 , 300 3. 45 , 315 correct 4. 90 , 270 5. None oF these 6. 30 , 330 Explanation: cos θ = 2 2 θ = 45 and θ lies in Quadrant I or IV. θ 1 θ 2 Thus θ 1 = 45 and θ 2 = 360 - 45 = 315 . 002 (part 2 oF 4) 10.0 points b) Express the above answer in radians. 1. 0 , π 2. π 4 , 7 π 4 correct 3. π 3 , 5 π 3 4. π 2 , 3 π 2 5. None oF these 6. π 6 , 11 π 6 Explanation: 45 · π 180 = π 4 , and 315 · π 180 = 7 π 4 . 003 (part 3 oF 4) 10.0 points c) Without using a calculator, fnd two values oF θ that satisFy the condition cos θ = - 1 2 1.
