Useful homebrewed applications for Apple's iPhone mobile just keep coming and coming: Homebrew developer Markus Sintonen released iPlot, a graphing calculator that draws mathematical functions, which would prove to be very useful in classes. It can solve and find several factors, such as roots, minimum, and maximum.

This application can also let you do almost everything that is expected of a graphic calculator, including basic ones such as sin(x), ln(x), and even csc(x). As for the actual interface, iPlot proves to be quite versatile with its option to zoom in and out,  and even zoom to any defined region.

Those who are interested in grabbing this application may do so by downloading and installing it directly through the iPhone's Installer.app. Enjoy!
