SUMMARY

The discussion centers on two primary issues faced by users of the TI-Nspire CX calculator. First, users are unable to easily reuse previously typed equations, unlike the TI-89, where the "2nd + Entry" function allows for quick retrieval. Instead, users must rely on the tedious "Ctrl+C" and "Ctrl+V" method for copying and pasting equations. Second, users seek a way to disable the touchpad, which causes frequent misclicks. While there are resources available for modifying touchpad settings, a complete disable option is not clearly outlined in the documentation.

PREREQUISITES
  • Familiarity with TI-Nspire CX calculator functionalities
  • Understanding of basic equation manipulation techniques
  • Knowledge of keyboard shortcuts for copy and paste operations
  • Awareness of calculator settings and configuration options
NEXT STEPS
  • Research TI-Nspire CX equation editing features and shortcuts
  • Explore the TI-Nspire CX user manual for advanced settings
  • Investigate third-party resources for disabling the touchpad
  • Learn about alternative methods for managing complex equations on TI calculators
USEFUL FOR

This discussion is beneficial for TI-Nspire CX users, educators teaching mathematics with this calculator, and anyone seeking to optimize their calculator experience by understanding its features and settings.

Sorry, title limited on what I could type. I just got this calculator and am having two big issues with it.

1) I cannot figure out how to reuse my most recently typed equation. For example if I type in a insanely long multiple variable equation and evaluate, the only way I can figure out how to get it back is to type it all out again, if I want to change something and re-evaluate. On my Ti 89 I could just do 2nd + Entry.

2) How can I disable the touch pad? I have no desire to use it and I see no reason to use it, and it is causing me to misclick through the menus way too often.

Hm the ctrl+c and ctrl+v combo works for the equations I tried, but it's a little tedious.

I had tried scrolling up and clicking to bring the equation back down, but I specifically was unable to get this to do anything with summation operations. The copy and paste method should make due for now... thanks!
