TI-Nspire For Dummies

From TI-Nspire For Dummies, 2nd Edition by Jeff McCalla, Steve Ouellette

The TI-Nspire device is the most sophisticated handheld graphing calculator available, allowing users to display and evaluate values symbolically, and to reuse the same equations across multiple applications. Because it’s so sophisticated, navigating its features can sometimes be confusing. It helps to know a variety of methods of achieving your aims with the device.

Computer Keyboard Shortcuts for TI-Nspire Software

Sometimes when you're using a computer, you get into typing mode. Call it laziness if you want, but you might not really feel like accessing a symbol palette or catalog to insert the symbol or command that you need. Incidentally, the first seven shortcuts also work on the handheld:

  • To enter π, type pi.

  • To enter θ, type theta.

  • To enter ∞: type infinity.

  • To enter , type <=.

  • To enter , type >=.

  • To enter , type sqrt(...).

  • To enter ǁ, type abs(...).

  • To enter i (the imaginary constant), type @i.

  • To enter e (natural log base e), type @e.

  • To enter ° (degrees), type @d.

  • To enter r (radians), type @r.
