Discussion Overview

The discussion revolves around the search for free integral solvers capable of handling multi-variable problems, with participants sharing their experiences and suggestions regarding various tools and software for integration, particularly in relation to the TI-89 calculator.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about free integral solvers that can handle multiple variables, expressing dissatisfaction with the TI-89's capabilities.
  • Another participant shares a recommendation for a single variable integrator, noting the limitations of the TI-89.
  • A suggestion is made regarding affordable options for students, such as Mathematica for Students or Maple Student Edition, although these are not free.
  • A participant introduces Virtual TI, an emulator for the TI-89, detailing its features including support for multiple calculator ROMs and debugging capabilities.
  • Another participant shares their difficulties in getting the emulator to work, specifically with obtaining a ROM dump using a TI-89 and a Graph Link cable.
  • Technical advice is provided regarding the installation of drivers for the SilverLink cable, with references to various resources for troubleshooting.
  • A later reply confirms success in getting the emulator to work after following the advice given.

Areas of Agreement / Disagreement

Participants express a range of opinions about the capabilities of the TI-89 and the availability of free integral solvers. While some suggest alternatives, there is no consensus on a specific free solution that meets the initial inquiry.

Contextual Notes

Limitations include the lack of clarity on the effectiveness of the suggested software for multi-variable integrals and the dependency on specific hardware and software configurations for successful operation of the emulator.

Who May Find This Useful

This discussion may be useful for students and users of the TI-89 calculator seeking alternatives for integral solving, as well as those interested in emulator options for TI calculators.

Are there any free integral solvers? Preferably one that can handle more than 1 variable. My ti-89 does not like a few of the integrals I gave it.
 
Physics news on Phys.org
Here's a nice single variable integrator. I use it all the time.

I also have a TI-89. It's very limited.
 
Even though they aren't free, you can get Mathematica for Students or Maple Student Edition for a very low price - that is, if you are a student, of course.
 


I have located an excellent emulator for the TI-89 calculator, called Virtual TI (v2.5 b5).

This emulator will run ROMs from the TI-82, TI-83,
TI-83 Plus, TI-85, TI-86, TI-89, TI-92, TI-92 II,
and/or TI-92 Plus calculators.

It has a routine for uploading your calculator ROMs directly into the emulator.

It is possible to compile your TI programs with the emulator and download them to your TI calculator and vice-versa.

It can also 'save states' and has an excellent debugger.

I've been trying to get VTI to work, but I can't seem to get a rom-dump. I have a silver Graph Link cable and a ti-89. Do you have any suggestions?
 
SilverLink cable (TI-GRAPH LINK USB) drivers...



Try installing TI-connect listed in reference 1.

Uncertain if reference 3 is the correct driver for your system, try consulting reference 2 listed below, then determine what driver link software is appropriate for your system.


Windows Driver for TI-GRAPH LINK USB cable, v3.0 (binaries)
Installation disk of the TiglUsb driver for Windows. This driver handles the new TI's USB link cable (aka SilverLink). It's needed for USB support with TiLP for Windows. New: sending transfer are now quite fast.
