Question
1. Which is NOT part of an accurate description the region given by the polar bounds 2 r S 5,3m/4 5m/4. (A) It is a wedge shaped region in between circles of radius 2 and 5 (B) It starts at an angle of 7 above the negative x-axis and sweeps clockwise T/4 to an angle of 4 below the negative x-axis. (C) The edge of the inner circle is not included (D) The edge of the outer circle is included 2. When converted to rectangular coordinates, the points (a) (2,2T/3), (b) (4,3T), (c) (-2, -5T/6) have rectangular coordinates (a) (A, B), (b) (C, D), (c) (E, F) respectively. Four of the numbers A, B, C, D, E, F are integers (the other two are both V3). Enter the sum of those four integers. 3. When converted to Cartesian form, the curve r 2 sin 6 2 cos 0 has the form (z -A)2 (y B)2 2. Enter the sum A B 4. When converted to polar form, the curve 2 y 9 has the form r A. What is A?Explanation / Answer
1. C
2. 1-4-0-1 = -4
3 A=B=1; A+B=2
4 r=3 ; A=3
