Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points Evaluate the integral I = integraldisplay / 2 (1- 4 sin 2 ) d . 1. I =- 2. I = 1- 1 4 3. I = 1 4 - 1 4. I =- 1 2 correct 5. I = 3 2 6. I = 3 4 - 1 Explanation: Since sin 2 = 1 2 parenleftBig 1- cos 2 parenrightBig , the integral can be rewritten as I = integraldisplay / 2 braceleftBig 2 cos 2 - 1 bracerightBig d = bracketleftBig sin 2 - bracketrightBig / 2 . Consequently I =- 1 2 . 002 10.0 points Evaluate the indefinite integral I = integraldisplay 2 cos 4 2 t dt . 1. I = 1 4 parenleftBig 3 t +sin 4 t + 1 8 sin 8 t parenrightBig + C correct 2. I = 1 4 parenleftBig 3 t- cos 4 t + 1 8 cos 8 t parenrightBig + C 3. I = 1 4 parenleftBig 3 t- sin 4 t + 1 8 sin 8 t parenrightBig + C 4. I = 1 4 parenleftBig 3 t + cos 4 t + 1 8 cos 8 t...
