In this assignment, I will be exploring the
The graph of
graph of and some of its its variations
We see that the graph ofis
a circle with radius of 3 and the origin as its centre. The radius
of the circle will always be the square root of the constant value
(in this case 9).
When we add the term xy to the equation of
the circle, the graph becomes an ellipse. To see the mathematics
related to this process, click here.
We see that the ellipse get "stretched"
when we increase the coefficient of the xy.
The graph of is a
big ellipse. You can see part of it in the graph above.
Now an interesting thing happens. The graph
of is no longer an ellipse. The graph is
now two curves with the straight line y = -x as the axis of symmetry.
