Ok, then tell me mister TI-92... can you tell if the derivative expression forisCode:`y = sin(x^(1/2))+(sin(x)^(-1/2))`

:confused:Code:`[cos(x^(1/2))]/[2x^(1/2)] + 1/[2(sin(x)^(1/2))]`

don't test the 92 or the 89... they are massive beasts of knowledge.

And if I was home or could remember anything from any of my calc classes, I'd do that on paper. - 09-30-2002dbarylQuote:

Attached you'll find a screenshot of an emulater TI-92 Plus with that problem. Seems correct to me :)

As you can see, there's a MINUS and not a plus in there. - 09-30-2002Aran
wow, that's one whacky emu, where'd you get it from?

I think this link should do it:

http://www.ticalc.org/archives/files...o/84/8442.html

although I know I found it elsewhere. Emulates anything from 82 to 92+, with the right roms. The download on that page includes all of these.

I actually own a 92 (which I hate cause of it's size) as well as a 89 and 83. I think there's no real need for the 92 in any case, 89 can do it all just as well, except for QWERTY keyboard and some memory. Plus, an emulator doesn'r really care how much "memory" you have now, does it? ;)

lots more links there... thanks google :)

There's some sweet stuff here, as well as a programming tutorial for TIGCC, a version of C for TI. - 09-30-2002BMJ
We should have an emulator contest!
