Tutorial Exercise Convert the polar equation to rectangular form and sketch its graph. r = 9 cot(8) csc(0) Step 1 The polar coordinates (r, 0) of a point are related to the rectangular coordinates (x, y) of the point as follows. x = r cos (0) y = r sin (0) Step 2 The given polar equation can be rewritten as follows. r = 9 cote csce r = 9 cote y = sin (0) 9x = sin = 9 cote Converting to rectangular coordinates using x = r cos 0 and y = r sin 8 gives 9x ✓ V cos e y Step 3 Sketch the graph of y² = 9x. sin 0 9.x 1 sine y² y
