upcoming mathematics suite - beta testers?

[PocketMath]

Hello.. I am working on an advanced mathematics suite for the Pocket PC. I am surprised that with the speed of Pocket PCs there hasn't been a large number of these. (It has advantages over the HP49G emulator, especially speed and graphing ability).

It is on the level of a TI-86, with some features of the TI-89, and graphing capabilities that far surpass any graphing calculator. It will have, for example, 2d explicit/polar/implicit/parametric, 3d explicit/parametric, fractal generating, etc. The 3d functions can be rotated by dragging the stylus around on the graph window, which is rather easy (and entertaining :) ). On the iPaq, the precalculating time for a typical high quality (albeit wireframe) 3d graph is well under one second and the graphs rotate extremely smoothly.

The majority of its functions are extended to the complex plane (ie, e^[i*pi] will give -1, arcsin(5) will give about 1.57-2.29i). It has a few common special functions such as the gamma function, and can find numerical approximations for derivatives evaluated at a certain point and definite integrals. I have finished an algorithm for finding the derivative as a function, but the simplifying needs work. It is not intended to be a CAS, however.. only an advanced calculating utility with unmatched graphing features.

Anyway, I am looking for some beta testers with a reasonably strong background in mathematics who would be able to help find errors or unsastisfactory accuracy in results. It may be a month or two before it is even ready to be tested thoroughly, but I figured I should start generating some interest. Let me know if you would like to be a beta tester or simply want to show interest :)

As a student who currently carries a bulky TI-89 around, I would love to be able to (for most situations) have everything at my fingertips at my iPaq.

I don't think I have enough background experience to beta, but I'll be waiting to hear about a release :D

I would love to beta test (I have a mono ipaq-3100 and an HP Jornada 548). I have been waiting for a program like this. For now, I have been using Salitare Xpander, supposedly that was supposed to be on the HP Xpander calc. Anyway, I have both a 49g and 89 and i'm in calculus right now so i can test out many math features for you. Email me at [email protected] if your interested.

I'm a senior EE student and have been carrying my IPAQ and TI around for several years now (and yes I still use the TI-85 which I upgraded from my 83). I have searched the web high and low for a decent calculater for the IPAQ that can handle complex numbers half as well as TI. I may not be your greatest beta tester, but I would be happy to run the complex engine through it's paces. If your interested, let me know! I will definately be a customer!

I'm also a 89 toteing math student and would love to beta test with my iPaq 3850.

I would love to beta test. I use an iPaq 3835.

I am a TI-89 equipped high school student who will be in precalc next year.

I have used a TI-83 in the past but love my 89 because of the extra features. Stuff I use/like most:


o Pretty print - This allows me to easily check if I entered an equation or matrix correctly, or if I missed a neciassary pair of parens.

o Solving equations - The 89 can even solve for a variable in relation to other variables in the equation. It can also solve systems of equations for multiple variables.

o Fractions and radicals - The 89 is great because it keeps everything in an exact form, instead of converting it to decimal (unless you tell it to). I also like being able to type in "root 40" and it tell me "2 times root 10".

o Manipulation of quadratic equations. Expands and factors.

o Appropriet handling of imaginary numbers. I enter i^4 and it knows that is 1.

o Programmability. A must have for any graphing calulator.

o Advanced functions such as sigma.


One thing not built into my 89 but woulden't be to hard to add is support for conics. I would like to be able to enter an equation, and have it ouput the equation in the proper conic form, in addition to telling me the type of conic, its center, foci, verticies, and directrix, depending on the type.

I would gladly pay $30 to not have to carry my 89 to math class. Unfortunatly, I don't think any math teacher would let a student use an iPaq on a final, so I don't think it would be possible to use it as a full replacement.

Hello,

I would like to join as betatester, since I am the "president" of a Spanish Calculator User Club at my University. I've been using and programming HP calculators for years, and I am working as betatester in another math software that works in linux handhelds..

I have tested HP Xpander Software, but it is a poor math tool compared with HP49 machine, which should be consider as a reference.

Please contact me in my e-mail, I would share a lot of ideas I am working in...

Thanks,

PS:Calculators I use: hp20s, hp32sii, hp48g, hp40g, hp49g, ipaq 3130 (linux) + Xcas, Emu48 in PocketPC, Xpander math software,...

I am a 2nd year college student and I own an iPaq 3835. I am interested in testing ur software foor cal.2 next semester.

It’s great that your doing this, especially since you plan to do 3D graphing as well, I myself recently went hunting for some Graphing calculator software, and was able to find mostly emulator of real calculators, which wouldn’t due at all. However, I did find one Graphing Calculator program designed specifically for the Pocket PC by Pocket Innovations (http://www.pocket-innovations.com), and I thought you should know that it is out there, so that you can see what has been achieved so far on the PPC, and what you have to beat. I hear they plan to release a version 2.0 rather soon.

Here’s a link… (http://www.pocket-innovations.com/Products/index.htm), it’s the program called GraphIt, with ‘Pi’ as its logo…

Hi,
I've been looking for an emulator for the TI-85, but without luck until now, it seems.

Anyway, most of you may know VTI, an emulator (with free source code - Borland C++) for the PC... I'm surprised that nobody has 'ported' it to the PocketPC platform... VTI is very nice, it's skinnable, but you must use a ROM from the calculator you want to emulate. Have a check at http://www.graphics-studio.net/vtimain.php

If you want, I could test it on the iPaq 3870.

Regards,

Would like to beta test this program. I am Calculus teacher (IB & AP) and use TI-86's in class as well as TI-92's. I would pay up to $25 for a good version of this program that would run on my HP Journada 565.
Teachers would likely not allow the pocket PC to be used for exam purposes so the resale may be hard.

Apparently I forgot that I posted anything here :)
I've been pretty busy, so instead of posting here what has been happening with PocketMath (or whatever it will be called..), I will post a website with information once it is ready. It should be a couple of days.
