Test for symmetry and graph the polar equation. r = 9 cos (20) a. Is the polar equation symmetrical with respect to the polar axis? A. Yes. OB. The polar equation failed the test for symmetry which means that the graph is not symmetric with respect to the polar axis. OC. The polar equation failed the test for symmetry which means that the graph may or may not be symmetric with respect to the polar axis. == /? b. Is the polar equation symmetrical with respect to the line 0 = π O A. The polar equation failed the test for symmetry which means that the graph is not symmetric with respect to the line 0 = 2 π OB. The polar equation failed the test for symmetry which means that the graph may or may not be symmetric with respect to the line 0 = 2 O Yes. c. Is the polar equation symmetrical with respect to the pole? OA. The polar equation failed the test for symmetry which means that the graph is not symmetric with respect to the pole. B. Yes. OC. The polar equation failed the test for symmetry which means that the graph may or may not be symmetric with respect to the pole.
