Lemniscate Let d1 and d2 be the distances from the point (x, y) to the points ( –1, 0) and (1, 0), respectively, as shown in the figure. Show that the equation of the graph of all points (x, y) satisfying d1d2 = 1 is
This curve is called a lemniscate. Graph the lemniscate and identify three points on the graph.
