Where can I buy a graphing calculator? My parents wont let me buy a graphing calculator because I already have a scientific calculator. Now I don’t know what to do. It is required by algebra 1. Anyways I can buy it or sneak somehow?

Suggestion by Not me. Or is it… If you are buying it with your own money, I don’t see the problem with your parents letting you buy one… You can get them at Wal-Mart or Target, just to name a few.

Suggestion by Laci_Laine If it’s required you should ask your teacher to call and talk to them. A scientific calculator is not the same as a graphing calculator, as you know. Anyway, if you lived in the LA area I would give you my old TI-83, but these days they probably require a better model lol. It was top of the line when I bought it almost ten years ago! Try putting a want ad on freecycle.org, and in the free stuff section of craigslist, and in the want ad section with the amount you would be willing to pay. Or, if you have the money, just buy one at wal-mart, target, or any other store like that (after the teacher talks to your parents!). If your parents won’t budge on it, your math teacher probably has one you can borrow, after he realizes how unreasonable they are being. The teachers at our school always had some extras that kids who’s parents couldn’t afford to buy them were allowed to use. And for people who forgot them that day. Hope it all works out for you!

Suggestion by Roshan You can buy one from Wal-Mart at around 90 to 100 dollars.

Are there any computer applications that simulate a graphing calculator like a Ti-84? Doesn’t matter if they are free or not, just looking for an application like this.

Suggestion by Ryan C maple, but i believe it’s pricey

Sage, however, is a free alternative..

Online college class? So I'm taking General Psych, Intro to art, College Algebra, and College Writing. But I was thinking of either dropping the writing ...

I just bought my daughter a TI84+ at target for $ 88 and walmart has them for $ 90. The math department should have graphing calculators to lend you and sometimes the local library does too. I did not understand why we needed to buy another expensive calculator-because I really did not understand what advanced ones really did. The teacher can send a memo home with instructions.

I havent used any of the free ones, but i am sure some of them could do the stuff that a graphing calculator. Though if you want an actual graphing calculator program, see the first link i posted.

Yep…You can get the ‘Virtual TI’ program which will look and act like a TI-82, TI-83, TI-83 Plus, TI-85, TI-86, TI-89, TI-92, TI-92 II, and TI-92 Plus.

There ya go!

Theres a TI-89 emulator i found online a while ago ( http://mathematics.mc.maricopa.edu/seims/TI-Emulator.htm ). The TI-89 is a nice calculator with a built in Computer Algebra System.

There are other commercial programs that are very nice, like Mathematica, but they are generally quite expensive…

Theres a list of different CAS’s on Wikipedia ( http://en.wikipedia.org/wiki/Comparison_of_computer_algebra_systems ), it lists a lot of free ones, and commercial ones (like Maple which costs $ 2375 and Mathematica which costs $ 2495).

Yeah, there are computer applications that not only simulate/emulate a graphing calculator, but can emulate a TI-84 Plus specifically.

Virtual TI is obsolete and can’t emulate the TI-84 Plus, although it can emulate a very similar calculator, the TI-83 Plus.

To emulate the TI-84 Plus, I recommend TiLem, which works on Windows and Unix-based operating systems (for Windows… http://www.ticalc.org/archives/files/fileinfo/372/37211.html), and WabbitEmu (Windows binary http://www.revsoft.org/wabbitemu.zip and Mac binary http://www.revsoft.org/phpBB2/viewtopic.php?t=745, source at http://svn.revsoft.org/wabbitemu/).
