Need a good non-graphing calculus calculator that can derive and integrate

Question

It's my 3rd time going through Calculus II and I want to pass this class already. I'm not trying to cheat I just see people with fancy calculators and I have never even used a calculator on tests before.

I just want to shorten the time it takes to compute fractions, double check my derivatives and antiderivatives, and speed up my test taking in general. One that could do limits and other stuff like that would be cool too.

Any little known programs worth mentioning? I'd love to have the step-by-step derivative/integral solver

Answer 1

A calculator is very unlikely to solve your problems for you. Having taught for a lot of years now, I set up tests so that they measure student's understanding'not the tools they happen to have at hand.

Concentrate on understanding the subject matter. Yes, that means studying to understand the subject matter after each class, doing exercises, checking other material (lecture notes, web, ...). Sorry, there is no royal road.

Answer 2

The calculator may not solve your problems but the casio fx991ES plus is very useful for checking your answers. It only does definite integrals and derivatives and is fairly cheap to buy

Answer 3

The best calculator, in my opinion, is the TI Voyage 200. Besides Integration and Derivatives displayed in Pretty Print, it even does some Differential Equations.
