For those doing secondary mathematics, this free on-line graphing calculator may be of interest. For those who have iPads, there are free graphing calculator apps available, but it is nice to have one available on a home or laptop computer as well. Besides being helpful for completing homework assignments, the graphing calculator is a great learning tool as well. For example, by comparing the graphs of particular equations [such as those for x^2, x^2 + 3 and (x + 3)^2] one can gain an understanding of how a graph is translated on the Cartesian plane.
