I have a TI-89 titanium and I love how it displays the equations after I enter them so I know if I entered everything correctly, it is way to big to carry around though. Does anyone know of a iPhone calculator that gives a readout like the TI-89 titanium?

Thanks

I don't know what that is...:eek:

If you rotate the phone into landscape the calculator turns into a scientific calculator, if that helps?

Don't think there is. It seems more suitable for an iPad anyways. The screen is probably too small to fit all that in.

No not at all

The TI-89 has pretty print where you can view the input and output of what you enter

The built in calculator does not show anything close to that for its display

Here is what we are talking about

The closest thing is RK-89.

Texas Instruments should consider producing the TI 89 (or even 83, 84, or even 92) interface app. $$$ for them. Because I would buy it, even near it actual price of the calculator.

Man I loved my TI-89 when I was in high school. It played a very large part in me passing my AP Calculus class. :) I can't believe the TI-89 is still around nearly unchanged, as this was back in 2000-2001.

PocketCAS and SymCalc both work very well.

I think maybe SymCalc is a little easier to use but both have some minor quirks.

Pi cubed and wolfram both look pretty good. Thanks for the suggestions.

They would have been good back in high school or even college, but my teachers never let us use any thing more than a scientific calculator.

I can vouch for Wolfram Alpha. It can solve almost anything math related that I've put in. I've used it for College Algebra and Calculus I. It can do pretty much everything the TI-89 can as far as solving problems like derivatives, integrals, limits, etc. You just have to know how to write it in the text box. Here's an example, based on the full website of Wolfram Alpha. Plus, the iPhone application has a special keyboard with symbols like the square root and the integral symbol, which saves a lot of time.

Oh you MUST try out MatCalc. As a math major, it comes in real handy as a speedy calculator that has all the functions of a scientific calculator and more. But the best thing is that you can design equations in there, have everything show up exactly like on a TI calculator. Like you can define your own variables and stuff. But also there's a papertape, and you can save it if you're doing a string of calculations. It helps when you need to use the answer of a previous calculation in the next one and stuff. Plus like a TI, you can write and run your own scripts for more advanced stuff.

Basically its a substitute for the native iPhone calculator app as well as being an advanced TI calculator without the graphing ability.

only calc I know of that has pretty print is 'SpaceTime'.



Not exactly the same as ti-89 (input wise), but the best I've found so far.

I'm an engineering major, and love love love the TI-89.
I agree that it's too big and bulky, and should be an iPhone app.
This being 2011, I feel that it shouldn't be too daunting of a task for such a successful company like Texas Instrument. I can live without my flying cars, but a TI-89 in your pocket can't be impossible.

I've tried to find good calculator apps before. pi^3 is good, but doesn't have everything. The Wolfram Alpha app is cool, but the interface is nothing compared to the TI-89. Not only that, Wolfram requires the internet, which is generally a big no-no come Calc 2 test day. But getting a TI-89 app, setting your phone to airplane mode, and letting the teacher watch your every move to make sure you're not multitasking to Evernote or Wolfram with that iPhone 4, and you might just be in the clear.

I advise all people who agree that TI should create an application for the iPhone/iTouch should let your voice be heard by TI. Let's all write em a sternly written email or something. Who's with me?

The only thing that rivals the Ti-89, besides software like Mathmatica, etc is wolframalpha.com.

They have convenient apps for iOS and android as well.

This will definitely do exactly what you are asking for.
