Question #32b6a Trigonometry 1 Answer Rhys Dec 9, 2017 # r = 7/(sin theta) = 7csc theta # Explanation: We must use our polar co-ordinates knowledge; # x = rcos theta # # y = rsin theta # # r^2 = x^2 + y^2 # # theta = arctan(y/x) # so hence: #y=7 => rsin theta = 7 # #=> r = 7 /(sin theta ) = 7csc theta # Answer link Related questions How do I determine the molecular shape of a molecule?
