Graph the function (x – 2)² + (y + 3)² = 4 in Desmos. The points on this circle can also be represented by x = 2 cos(0) +2, and y = 2 sin(0) – 3. What is the amplitude of each of these functions? What is the midline of each function? How do the midlines and amplitude relate to the circle you see in Desmos?
