## Graphic Calculator on the Nintendo DS

I have a playstation portable but I really wish I had a Nintendo DS – take a look at this piece of freeware!

According to the software’s website it has the following features

- Evaluates mathematical expressions… including those with exponents, trig, and logarithmic functions
- Includes a CAS to simplify algebraic expressions, including foiling
- Graphs Cartesian, parametric, and polar equations, as well as slope fields and Euler’s method
- Catalog with many different functions
- Evaluates numerical derivatives and integrals, as well as Riemann sums

This seems to make really good use of the dual screens of the Nintendo machine and you can’t beat the price. If anyone out there has the required hardware to play with this then I would love to hear how good it is. A legitimate reason to get a games console into a Math’s class perhaps? ;)

I have one. But I prefer to play “Advanced Wars”. Seriously though – you should get one games are cheap and much easier to play then on the PSP. Also the battery life is great.

If you have a PSP, you can get a custom firmware and install a Ti-92 Emulator which is probably just as good as this.

I am aware of the PSP Ti-92 emulator but have never looked into it because of the lack of touchscreen on a PSP. I imagine that it would be rather fiddly to use.

My daughter just turned 10. We brought her the math game for nintendo ds to do multiplication. She has had the ds for about a little over a year. I had no idea that there was a calculator attached to it. I guess the $129.00 that we spent on it was really worth it. My three year old uses the math game to do addition.
