I am taking university calculus, and we are not allowed to use graphing calculators on tests. I was wondering if there were any calculators on the market that took derivitives and integrals, but are not classified as a graphing calculator.

The TI-68 does numerical integration (it might not, however be on the market).

OK I feel stupid, but maybe this will help someone in the future. I found the answer to my own question after about 4 hrs of creative eBay searching. The casio FX family of calculators does numeric diff and integration. I guess I should explain what the numeric part means, because I just learned what it meant. It means that it won't give you a new equation. It will evaluate definite integrals or give you a numeric value if you specifiy what x equals. This would be useful to help someone check their answers on a test. But you would still need to memorize all the integration rules, but have the ability to check your answers with test numbers. I wish they would let you use graphing calculators on tests in college math, but I guess it just makes it too easy to get an A

I have not heard of any calculators the will do symbolic derivatives or integrals. Symbolic integration even on a PC is tough to do.

Yes, there are various calculators which do symbolic integration and derivatives. Even DE's.

I have a Voyage 200 and a TI-92. They do these things, but alas are graphing calculators.

Here is a screen capture for kicks. The right one is a DE and the left shot is a symbolic derivative and integral.

Casio makes them as does HP. Maybe other models too. But I prefer TI.
