Integral solver?

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.
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.
