Ellipses & Hyperbolas

Drag the red dot to move the curve. Exercises for students

Sketch the following curves on paper and check your graphs using the above applet:

x2 + 16y2 = 16	16x2 + y2 = 16	(x - 2)2 + 16(y - 1)2 = 16	16(x - 2)2 + (y - 1)2 = 16
x2 - y2 = 16	y2 - x2 = 16	(x - 2)2 - (y - 1)2 = 16	(y - 1)2 - (x - 2)2 = 16
