We can clearly see the graph of a hyperbola ‘h’ in red with the equation -((x-l)/a)^2 +((y-m)/b)^2 =1. If we change the values of a, b, l and m using their respective slide bars we will see that the shape, size and position of the hyperbola gets changed. Let us observe how the size and shape of the hyperbola changes as we change the values of a, b, l and m.
Questions to think about 1. Change the values of l and m, what doyou observe? 2. Change the values of a and b, what do you observe?
