TI calculators are so last year. Especially with the popular (and free) Graphing Calculator application being distributed in the App Store by Gabor Nagy. This app is, basically, a colorful TI calculator right on the iPod. Although it may not offer every functionality of a TI, the Graphic Calculator app allows for the most popular tasks, such as graphing up to five functions (all viewable on the same graph), tracing and plotting points, and a root finder. And to top it off, the graphs are colorful, and you can use the pinch-gesture to zoom and scroll the graph, much like when browsing the internet in Safari. You can even take a screenshot of the graph and email it to yourself. As of the most recent update, the following mathematical expressions are supported by Graphing Calculator:

There is no doubt that with innovative apps such as the Graphing Calculator being released, it won’t be long before not-so-new devices such as the TI calculators become outdated. As far as I know, we need more apps like this to give us an excuse to play with our iPods in class.
