Unformatted text preview: roberts (eer474) – HW 09 – windle – (56747) 1 This printout should have 8 questions. Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Solve sin x (sin x + 1) = 0 for x . 1. x = 2 nπ, 3 π 2 + nπ 2. x = nπ, 3 π 2 + nπ 3. x = nπ, 3 π 2 + 2 nπ correct 4. None of these 5. x = 2 nπ, 3 π 2 + 2 nπ Explanation: sin x (sin x + 1) = 0 sin x = 0 or sin x = 1 x = nπ or x = 3 π 2 + 2 nπ 002 10.0 points Find all solutions of sin 2 x = √ 3 2 in the interval [0 , 2 π ). 1. x = π 3 , 4 π 3 , 5 π 6 , 7 π 6 2. x = 2 π 3 , 5 π 3 , 5 π 6 , 11 π 6 correct 3. x = π 3 , 5 π 3 , π 6 , 11 π 6 4. None of these 5. x = 2 π 3 , 4 π 3 , π 6 , 7 π 6 Explanation: sin 2 x = √ 3 2 2 x = 4 π 3 + 2 nπ x = 2 π 3 + nπ x = 2 π 3 , 5 π 3 or 2 x = 5 π 3 + 2 nπ x = 5 π 6 + nπ x = 5 π 3 , 11 π 6 003 10.0 points Find solutions for csc x 2 = 0 on the interval [0 , 2 π ]....
