3. = (a) Find all angles in the domain - a to such that tan(3x) = -1. (b) Show that (8 marks) (3 marks) cos e cote 1 - sino 1 = csc (C) Using Part (b), find all solutions to (5 marks) cos O cot O = 2(1 – sin o) 1-sine (d) By using Part (b) again, find the gradient of the function cos& cete at 0 = (4 marks) (20 marks)
