The differentiator and integrator in the TI-89 is probably a larger program than the TI-83 has RAM. So, to answer your question: no. none exist.

There is a program for CP/M called MuMATH written by microsoft that does derivatives. CP/M was an old operating system for the Z80 processor. If you can find the source code to MuMATH, it could possibly be ported to the TI-83. Remember though, that the Z80 has 64k of RAM but the TI-83 divides it into 32k ROM and 32k RAM. So, MuMATH may need 64k of RAM to run...

As for integration.... well, I can probably safely say that there's no way it's gonna happen with only 32k.

Is there a program for the 83 that does derivatives? How about integrals? I would use my 89, but my teacher knows that it can do these, and wont let me use it on tests. My teachers lets everyone use 83s, so I would like to have a program for the 83 that does both integration and differentiation.
