Sketch a graph of the polar equation and find the tangents at the pole. 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 e and y = r sin 8. The original polar equation can be rewritten in terms of x and y as follows. r = 4 sin e 2 - 4 sin e Since x = r cos e and y = r sin 0, x2 + y? = r?. Use this to rewrite the polar equation in terms of x and y. x² + y2 = 4
