According to research published in 2002 by Janice Scheuneman and Wayne Camara (PDF), girls used calculators on the SAT exam much more often than boys. White students used them more often than other racial/ethnic groups. Those who used calculators performed better on the SAT than those who didn’t – but the type of calculator mattered significantly: students who used graphing calculators outperformed those with scientific calculators, and those who had only a four-function calculator performed only slightly better (~20 points) than those who didn’t use a calculator at all.

That’s borderline creepy.

If you have the ti-84 there's no reason to use the Casio. It does everything the Casio does and more. (unless that's not the case) but all of the functions you showed are included in the TI. Also it's kind of a weird comparison considering the TI is a graphing calculator and the others are not. That being said the TI it horribly overpriced. I'd suggest the TI-Nspire CAS if you have the money. It does indefinite integrals and such.

fx-570 ES plus is such a powerful tool, and I just wanted to show off some of the basic, yet extremely useful things I do with it throughout my studies.

I roughly cover: - Complex Numbers - SOLVE - Simultaneous equations - Integrals Riemann Sums - Base conversions

There's much more info found in the manual.
