iPlot is a graphing calculator on the iPhone! I think the last time I used a graphing calculator was in High School and I’m not sure I really understood it then! So, I will do my best. Here is a description, via the developer, of what the app does.
“Program draws mathematical functions. It can find roots, minimum, maxium and integrals of functions. You can also draw derivate of functions. You can add up to 20 functions to graph. IPlot has a lot of different elementary functions. For example: sin(x), ln(x) also some rare ones: csc(x)… You can do all the necessary graph manipulations: pan, zoom in and out, zoom to defined region and set graph limits by hand. See more about features in help section of program.”
When the app opens, you will get the main screen. From here you can go into the Options, Help, Plot which bring you to the actual graph and Add which allows you to add a function and choose the color of the line. Once you have everything set the way you would like it, select plot which will open the graph. Just tap and drag to move the graph around. You can single tap to get a menu bar with more options for the graph. Double tapping will bring you back to the main menu. This app seems like it would very handy for people who use this type of thing. It has an easy-to-use interface and seems to be a sturdy app. iPlot if available through the BigBoss source.
