graphDS is a graphing calculator application designed for the Nintendo DS. Currently, the program is capable of evaluating mathematical expressions and Riemann sums as well as simultaneiously graphing up to four Cartesian, parametric, or polar functions.

Release notes:

Here’s graphDS v0.4. I added a feature that lets you adjust the graphing window and the starts, stops, and increments for parametric and polar graphing. I also fixed the function input so that you can enter functions that are as long as you please. On the graphscreen’s keyboard, I added a delete key, e, pi, and y (note: the y variable can only be used for slopefields and Euler’s method, which currently cannot be accessed in the program).
