Calculators

i have to take Calc 1,2,3 / Linear /DE....

i will be allowed to use a calculator for all of my math classes....

i have a an 83, but i want to get a better one..

is the best one for me an 89???? or something newer/better out there...

thank you in advance

ti-89 is what S has been using since senior year of high school. He is junior in school of engineering. He loves that calculator.

You can also check you the new TI-nspire series, especially the CAS edition (equivalent to the ti-89). They are much more advance that the previous models (and slightly more expensive), but they are worth it.

You can also look at the HP calculators. I have heard very good things about them and some people absolutely swear by them. I've always used the TI-86 and the TI-89.

I have a TI-89 Titanium, and I love it, baby.

I have a TI-89.. and it has never let me down for any class.

I love the Ti-89. It does calculus for you and you can load programs onto it that do differential equations for you. Plus the games are better than Ti-83's.

TI 89. It is so powerful it is not even fair for ppl without it.

The most powerful calculators on the market are the Texas Instruments TI-89 and the Hewlett-Packard HP-50G.

The TI-89 is easier to use and is very popular with undergraduates (most of whom are familiar with TI graphing calculators from high school).

The HP-50G is more powerful and customizable than the TI-89; however, it is also more complicated, and more difficult to learn to use effectively. It is really designed for experienced professionals, not students who are learning about calculus or linear algebra for the first time.

No, the most powerful calculator right now is the TI-Nspire CAS. It is a successor of the Ti-89.

The TI-Nspire has some impressive capabilities for classroom use, but is surprisingly poor for programming. It therefore lacks the flexibility of a conventional graphing calculator.

The rumor is that TI crippled the programmability deliberately, to the Nspire from being used as a platform for games.

Don't know if they are made any more, but I have a HP-15C. Bought this in 1981 and have used it almost daily since. It got me through engineering and MBA school as well as numerous jobs. Probably my most reliable possession.

I will second the HP-15c (they don't make them anymore, but go for a couple hundred on eBay). I inherited one, and it's the only "calculator" I use for my classes. If I need to do anything more complicated than scientific computations, I use mathematica. Ultimately, it doesn't matter how powerful the handheld calculator is, you still have to type on it- and a computer keyboard is usually a lot faster than a handheld calculator, especially when you have to deal with variables and functions.

i bought the ti 89T on saturday. the calculator is insane ! I ve never had trig before so it comes in extremely handy...
