A powerful mobile math/science computing platform/web tool

[Gauss Math]

*Note: This math tool is for *educational/academic purposes ONLY* to solve larger scale math/science problems.

 

My friends and I are working on a public mobile computing platform that could be of interest to this community.

 

The URL is at: http://www.rapidcalculator.com

 

Instructions to use is at: http://rapidcalculat...com/syntax.html

 

RapidCalculator.com is a free mobile large-scale computing platform (this is like a heavily souped up TI-83 or TI-89). We create the capability for users to perform heavy scientific/math calculations on the web or on their mobile devices.

 

Perform intensive math/science/engineering calculations, matrix operations like multiplication/inverses, plot graphs of functions, operations on polynomials like multiplication/differentiation/integration, evaluate Fast Fourier Transforms, manipulate complex numbers and much more! Does not require any installation or plugin.

 

This tool is currently still under continuous development and enhancement (this is our first stable release), and we appreciate your feedback! Let us know what math functions that we should add, and what features would generally be useful for scientists/engineers/students/teachers. If it is feasible we will try to program it in. We are continuously adding new technical functions.

 

 

To start you guys off, as an initial math problem you could perhaps expand the polynomial (x^2+2x+1)^999. This is hard by hand calculation, but in RapidCalculator you will just type the command:

 

poly_x[(x^2+2*x+1)^999]

 

and see the results! Your graphing calculator will probably not be able to display this (we tested this on the TI-89), but not this platform! A lot of the calculations not possible on your graphing calculators/mobile devices will be possible on our computing platform.

 

 

Thanks, and we appreciate feedback!

How is it better than the already available wolfram alpha?
http://www.wolframalpha.com/

It computes the answer, gives the graph, provides the range and domain, and also shows alternative ways to express it.

I wanted to check on some algebra (I am soooo bad at getting signs right I nearly always check stuff via my PC or phone) - like Mellinia my go to ap for this is wolfram-alpha.

 

I was using my iphone 4 (something g ? S?) and tried the same things on both

 

Pros over Walpha

Nice long entry window that you can move along with a swipe cos you are viewing a section of a larger page

 

 

Cons

No custom keyboard! Plus, caret, times, equals, the braces, and greater than less than are all on the auxiliary keyboard

Very unintuitive - functions mixed with trig mixed with matrices etc

If you have a button marked sin - would it not be cool if when you clicked it the cursor ended up in the brackets?

It's not a mobile platform - but see above that might not be too much of problem

Your instructions have "math processing error" all over them

 

 

 

Just a first few thoughts - it needs a lot of effort to even come close to Walpha I am afraid.

 

Good luck
