We can clearly see the graph, of an ellipse ‘c’ in red color, equation of which is (x/a)^2 +(y/b)^2 =1. If we change the values of a and b using their corresponding slide bars we will see that the shape and size of the ellipse gets changed. Let us observe how the size and shape of the ellipse changes as we change the values of a and b.
