I am looking into buying a new calculator.. and I want to see what some of you guys use ....

Please specify what you use it for and if you consider worth the money you spent, also provide the amount you spent. Thanks.
I am thinking a TI ... any suggestions?

Also is there any really good one that is software base to just install on your computer.. I currently have GraphCalc on here.

I use a TI-89. I like it because it has a long memory of entries (30 recent actions) and has an easy to use numeric solver.

Do you think it was worth the cash?

in what field if any do you specialize?

Ti89 is my next best thing besides my handy AK47

I have a TI-89 too. It's really not very expensive, so yeah, it's worth the money. As far as software for a PC, look into Mathematica, MATLAB, and Maple.

For a handy ti89... $150 retail, go to officedeopt online... use coupon code 44503032 and get $20 off and free shipping. :)

Somehow I got mine for $80 brand new... Some coupon stuff.

DOes anyone else use an HP "RPN" calculator? They were all the rage in the 80s, and now I can't go back.

TI-89 is what I use as well.

I use a ti89, but I also have an hp 32sii which is RPN. The ti89 is capable of integrating, differentiating and solving second-order differential equations. The hp 32sii is a scientific calculator and the only programmable one I know of. It can do numerical integration and can solve equations.

I would recommend both calculators for engineers, physicists and other people that do high level math calculations daily.

I still use my trusty TI-83

If I lost it, I'd buy another as soon as I was sure it was gone.

I have used it in every class I've had for the last 4 years.

Aerospace engineering.

I use a TI-83+, but I wish I had a TI-89.
My TI-83+ does basically anything I need. It can solve matricies, definite integrals (but gives very wrong answers when crossing over an asymtote), and derivatives. It can graph polar functions as well as single variable non-polar functions. For graphs, it can find the y value for a given x value, find where y = 0, find local minima and maxima, and intersection points. As for stats, it can plot stats, find the best fit line, and display the formula for the best fit line. For best fit line, it can base the formula as being quadratic, cubic, quartic, linear, natural logarithmic, exponential (a*b^x), power (a*x^b), logistic, or sinusoidal.
Overall, it's one hell of a good calculator.

Enigma, does your university really allow programmable calculators? The university around here doesn't allow for those because they can be used for cheating. Programmable calculators like the TI-89 can do indefinite integrations, derivatives, and make 3D graphs. Bring a TI-89 into a test at U of A and it might get taken away.

TI-83 Plus Silver Edition.

It has memory and its fast, but it doesn't have quite the capabilities of a TI-89. Being a student on a budget, I cannot afford to get another graphing calculator anytime soon.

I have Casio 800 something scientific for school. I really like it, but it can't graph. Put the buttons are put in very convenient postions so you can enter long things really quickly. I got it for about 12$.

I agree with Ebolamonk3y: I tried the AK47 and never looked back.

Ok, I'm wondering, what does a TI-89 have that a TI-83+ doesn't have, besides extra memory?

I have a ti-83+ but I don't use it ever... Actually, I hardly ever use a calculator. All calculators are banned in my multivariable calc class.
