First Steps with TI-Nspire™

Tutorial 1: TI-Nspire documents

What is quite different from the computer is that within one document you can have multiple pages or problems that can make use of the different applications. The spreadsheet on one page of a document can interact seamlessly with calculations done on a calculator page and graphs drawn on another. You can also have more than one different representation on one page.

This use of multiple representations is one of the many things that make the TI-Nspire such a powerful tool. So with TI-Nspire you first open a document, or start a new one, and then choose an application.

TI-Nspire:Home screen  New document  Choose application

Tip: If you would like to return to the document you are working on without inserting

a new page, from the Home screen select option 4: Current. You can do this by pressing 4 on the keypad.
