This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise Sketch a graph of the polar equation and find the tangent line(s) at the pole (if any). r = 4 sin(0) Step 1 The polar coordinates (r, 0) of a point are related to the rectangular coordinates (x, y) by x = r cos 0 and y = r sin 0. The original polar equation can be rewritten in terms of x and y as follows. r = 4 sin 0 calcPad 12 = 4 X sin 0 + - Operations Functions Since x = r cos 0 and y = r sin 0, x2 + y2 = 2. Use this to rewrite the polar equation in terms of x and y. X Symbols Relations x2 + 12 = 4 X Sets VO 0! Vectors Trig
