Plot x2 + y2 = 1 by solving for y in terms of x. Enter the two solutions as y1 and y2
Chapter 12, Problem 1(choose chapter or problem)
Plot x2 + y2 = 1 by solving for y in terms of x. Enter the two solutions as y1 and y2. (One is a positive square root and the other is a negative square root.) Use a friendly window that includes the integers as grid points and has equal scales on the two axes. Based on the Pythagorean theorem, explain why the graph is the unit circle in Figure 12-1a.
