this is abit off topic, but i seirously dont know where to ask..

i'm studying final year high school maths in australia nxt year, and we have choices to bring in any of the TI calculators into our exams and SAcs, includes the 83+, 84+, 89ti, voyage200).

just wanting to know which of these is best to purchase, i already own a 84+ but i really have a dilema on whether to upgrade to a CAS calculator like 89ti. The topics taht we do next year include calculus, trignometry, vectors, complex nmbers, kinematics.

also,i have some brilliant BASIC prgms on my ti 84+ at the moment, is there any chance i can still use these prgrms, (by converting or something) on a 89ti ?

be wonderful if i got some opinions and expert advice.
thank you

As for calculator models, if they'll let you use the Voyage 200 on the test, I'd say go for it. If they don't, grab an 89 Ti. My reasoning: I find the Voyage 200 easier to use, despite it being about twice the size. If you like the 89Ti better, or you have a compelling need for a calculator with a USB port, go with the 89.

As for the basic programs, they're not totally compatible, but it isn't a total chore to cross them over. A For loop is a good example:

82/83/84 series:

:For(X,1,30)
:"stuff goes here
:End

68k:

:For x,1,30
: ©stuff goes here
:EndFor

So you see, the 68k series' BASIC is slightly different, but not totally. It's kinda like TI-BASIC version 2.0, where the 82/83/84 series' is version 1.0.
For better-looking user I/O, you can use Dialog boxes instead of the HOME/PrgmIO screen. I actually never use the PrgmIO screen except for debugging.

thanks for the reply

i really dont know anything about programming for either of the 2 types of calculators.

is there a program out there to convert say,, 8xp file to a file which is executable in 89ti or voyage 200?

will it be a very big advantage i'll have , if i use a voyage 200/ or 89ti in contrast to a ti83/84+ (the calc most students will use) ?

what are the advantages / and disadv for
ti84+ and 89 titanium/voyager

and no, i dont wanna play games, so better games doesnt tickle my fancy that much.

i'd appreciate if more knowledgeable ppl give their opinion?

also-- is this the best place to post my kind of quesiton? is there like a forum on this website or something?

There's not really a translator I know of other than doing it by hand.

As for the advantages and disadvantages of the disparate models, search TI's site for "craphing calculator comparison" or similar and you'll get a pdf of way more info than most people would ever care about. I find it to be particularly complete, especially if you don't care about games.

Don't you just hate when your calculator craphs? ;)

Even more than typos.

Oh my GOD! PpHd and Kevin Kofler, don't you have personal e-mail addresses? I can't even read this page!

Without their comments, there would not be very many yet for this article.

It is much more fun doing it in front of the audience.

It is also boring to read that Kevin Kofler did some forks (oh yeah, that's a great work, but has it a plot?)...
