Calculators TI-89 vs. Titanium: Which Graphing Calculator Is Best for Calculus?

AI Thread Summary
When upgrading from a TI-84+SE for Calculus I, the TI-89 and TI-89 Titanium are the primary options to consider. The main differences between the two models are memory capacity and processor speed, with the Titanium offering enhanced features such as a USB port for easier data transfer. While the Titanium is more expensive, users note that the performance difference is minimal, and the additional RAM is often unnecessary for typical use. Both calculators are not allowed during exams, so reliance on them should be limited. The TI-89 is no longer in production, making the Titanium the more viable option for new purchases.

Hello all, I am a high school student, who will be taking Calculus I, I need to upgrade from my TI-84+SE so I am considering either the 89 or the Titanium. The only differences I know of are the memory and the processor speed. Are there any other differences?

Which have you guys used and liked?

I already ruled out HP, so don't bother trying to convince me! (I am a little resistant to change)

I know I cannot use the calculator on the exams or anything, but it will be useful for the SATs and more...

Any input is welcome.
Thanks a lot.

Get the titanium. Please please please, get in the habit of only using it to check your answers. Trust me on this.
 
Why the Titanium though? Its much more expensive, is the memory and speed worth anything? Does it make a difference?

I agree with that. My 89 is just as good as the Titanium, just without a USB cable. Yes, the clock is a bit slower but it doesn't make a noticeable difference. I prefer the 89's looks anyway.
 
Not much of a difference. It's nice to have the large amount of ram, but definitely not necessary. I've never come close to filling it, but if I need it, it is there.

The big difference is the USB cable. It makes it VERY easy to transfer data to the device. I've transferred some very useful software to my calculator, and it was very painless using the USB cable.

I wasn't aware of this when I bought the 89, but just so you know. You cannot use it on the PE or FE exam. So as I warned, make sure you do not become too dependent on it.
 
The original 89 is not in production anymore. So looks like you have no choice. Its not listed in the purchase section on Texas Instruments' website.
 

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'ChatGPT Examples, Good and Bad'

I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
