to (aqt73) – Challenge 6 – seckin – (54330) 1 This print-out should have 6 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. 001 (part 1 of 2) 10.0 points Determine the quadrant in which the angle lies. a) 1 . 893 radians. 1. None oF these 2. Quadrant III 3. Quadrant II correct 4. Quadrant I 5. Quadrant IV Explanation: Since 1 2 π < 1 . 893 < π , then the angle oF 1 . 893 radians lies in Quadrant II. 002 (part 2 of 2) 10.0 points b) - 0 . 353 radians. 1. Quadrant II 2. Quadrant IV correct 3. Quadrant III 4. None oF these 5. Quadrant I Explanation: Since - 1 2 π < - 0 . 353 < 0, then the angle oF - 0 . 353 radians lies in Quadrant IV. 003 10.0 points Evaluate f ( x ) = 3 sin x - cos 2 x at x = π/ 6. 1. f ( π/ 6) = 3 2. f ( π/ 6) = 1 correct 3. f ( π/ 6) = 3 3 4. f ( π/ 6) = 3 5. f ( π/ 6) = 2 3 6. f ( π/ 6) = 2 Explanation: Since sin π 6 = cos π 3 = 1 2 , we see that f p π 6 P = 1
