I guess it'd be ok to post this here...

Anyways I had a TI-86 for about 6 years and despite new batteries, the thing finally died on me. I am about to buy a new TI-89 Titainium, but just out of curiosity (if anyone has one), does the 89 do conversions, too? On the 86, you could do time, weight, etc conversions?

Just wondering.

the 89 does everything the 86 could plus about a billion more things

but if you're like me and ain't that smart, it takes a billion years to figure out those billion things.

I used my TI-86 till somone relieved me of it, then got a TI-89T because it was recommended to me

took me a little while to get used to the ui, but its nice. conversions are simple, 42_cm>_m

'dont think I'll ever use even most of the features on it, I pulled up the manual pdf on TI's site and its over 1000 pages..

I think that the biggest drawing card the 89 has is that it can do differentiation and integration symbolically and spit back a bunch of letters for your answer.

So, that's how I did calc III, completely. Triple integration all on one line.

^ yeah that's useful, also you might want to take a look at the HP 49g+. It's got more features than the ti89, a homework mode that shows you step by step solutions to integrals and algebra problems, as well as a million other little niceties. It's also about the same price, if not cheaper, than the ti 89.

And no, reverse polish is not required, you can set it on non reverse polish mode too.
