Q: QuestionCan the graphics on the ti 89's screen be displayed on a pc.
Asked by wallyh.
- A:Answer I have not done it yet but I believe you can. It comes with a wire that plugs into calculator and computer by the usb port. This site tells you how to connect and view the calculator screen on your pc. http://www.calcblog.com/articles-connecting-your-ti-84-ti-83-ti-89-or-ti-92-to-your-computer/ Hope this helps. It's a great calculator.

Q: QuestionWhat’s the difference between this & the TI-84+ ce ?
Asked by Kcubs.
- A:Answer The 84-Ce has better graphics, but the 89 does far more calculations. I can now do sim. equations, vector analysis, and much more. The 900 pg user manual tells it all in good detail.

Q: QuestionCan this TI-89 calculator copy and paste equations so you don't have to retype an equation over and over?
Asked by Levi.
- A:Answer Hi Lexi, You can copy and paste information like entries on the entry line on the home screen. Users may refer to page 211 of the TI-89 Titanium Guidebook for further reference, https://education.ti.com/en/guidebook/details/en/FA1DC891957E4700B46A67255850C592/89ti Cutting or Copying Information to the Clipboard When you cut or copy information, that information is placed in the clipboard. However, cutting deletes the information from its current location (used to move information) and copying leaves the information. 1. Highlight the characters that you want to cut or copy. In the entry line, move the cursor to either side of the characters. Hold ¤ and press A or B to highlight characters to the left or right of the cursor, respectively. 2. Press ƒ and select 4:Cut or 5:Copy
