Oliver (smo998) hw 10. 3-10. 4 rusin (52440) Multiple-choice questions may continue on the next column or page nd all choices before answering: true: 4 cos(4 /3) = 2 , 4 sin(4 /3) = 2 3 . Which one of the following shaded regions consists only of points whose polar coordi- nates satisfy the condition. C. (4, 7 /3) , (4, /6) , ( 4, 4 /3) , are polar coordinates for the point given in. Cartesian coordinates by p (2, 2 3): b and c only, a and c only correct, c only, none of them, b only, all of them, a and b only, a only. To convert from cartesian coordinates to polar coordinates we use the relations: x = r cos , y = r sin , so that r2 = x2 + y2 , tan = y x. For the given choices we thus see that: true: di ers from /3 by 2 , false: incorrect.
