You can run Maxima, a computer algebra system, on your Android mobile devices Mar. 31, 2013 Maxima on Android 1.7 on Google Play. https://sites.google.com/site/maximaonandroid/ Maxima, a full featured computer algebra system, now runs on your Android mobile devices. Maxima, and its predecessor Macsyma is one of the most long-established software in the world, back in 1960s at MIT LCS and Project Mac. You can perform many many math operations such as integration, differentiation, matrix operations, rational numbers, symbolic treatment of constants such as pi, e, euler's gamma, symbolic and numerical treatment of special functions such as sin(x), cos(x), log(x), exp(x), zeta(s), and many more. Maxima on Android is a port of Maxima on the Android operating system. Thanks to Sylvain Ageneau' effort on porting Embeddable Common Lisp to the Android OS, the latest Maxima code runs nicely on ECL on Android with very small changes to the source code. https://play.google.com/store/apps/details?id=jp.yhonda&hl=en At 11:19 AM 7/8/2013, Robert Baillie wrote:
I recently acquired an Android smart phone, and have been surpised at all the things it can do and the apps it can run.
I installed "Primality Test" by the Mincemeat team. This is the only prime testing app I could find that works with numbers of arbitrary precision. I didn't find any factoring apps that go beyond 10^18, and those appear to do factoring only by trial division. Are there better ones out there? (I'm already working on one for my own amusement, but I'd like to find a good one).
Just for fun, I installed a spectrum analyzer (Spectral Audio Analyzer by RadonSoft): it displays the frequencies in sounds that are picked up by the microphone.
What are your favorite math apps?
In particular, are there any calculators where you can type expressions (like "sqrt(-5) + sin(pi/7)^2") instead of just punching keys on a keypad?
