    Appendix: Factory Default TI-Nspire CAS ............... 109 Preface The purpose of this book is to make TI-Nspire CAS easily and quickly accessible, especially for teachers and students. Many thanks to David Stoutemyer who polished the language of this text and made valuable suggestions for improving the original manuscript.

  • Page 5: Introduction

    TI-Nspire CAS is a powerful mathematics tool suited for teaching and learning. It combi- nes several applications under one roof: A Computer Algebra System (CAS), a graphing soft- ware, an interactive geometry system, a spreadsheet, an interactive statistics system, a text editor, a data collection interface, and a programming environment.
  • Page 6 Have fun reading and discovering. For users of TI-Nspire™ : Most parts of this book do not use the CAS component of TI-Nspire ™ CAS. Therefore you can use this text also with TI-Nspire™. Only part of the “Introduction to the Calculator” is CAS specific.

  • Page 9 The following chapters provide independent introductions to the five main applications. The two applications contained in the Graphs&Geometry application are treated separately. A major strength of TI-Nspire CAS is the “roof” that connects the individual applications. The first part of the “Introduction to Combining TI-Nspire CAS Applications” introduces you to this “roof”.
  • Page 10 Handheld Now you see a picture of the TI-Nspire CAS handheld. You could go through the exercises of this book in this mode. Press a key by moving the mouse pointer above the key, and then clicking the left mouse button. You can enter numbers, letters, and special symbols also via the computer keyboard.

  • Page 13 Quick Start Guide – TI-Nspire CAS Software Delete the two symbols left of the cursor using the backspace key E ‹ | F two times. An alternative to entering a fraction as a linear input string is using the “2-dimensional” frac- tion template, which is similar to what equation editors offer.
  • Page 14 Most students strive to replace such an expres- sion by the corresponding floating point approximation 4.8989…. As explained later TI- Nspire CAS can do this as well. Any expression in the history area can be highlighted then auto-pasted into the entry line to be used to help build a new entry.
  • Page 15 Quick Start Guide – TI-Nspire CAS Software The symbols on the Calculator Toolbar’s second button, , indicate a conversion from an exact number to a floating point number (which may be an approximation). Open the menu by clicking the button with the left mouse button.

Open the selection menu of the input field by clicking the down arrow Display Digits button at the right end of the input field.
  • Page 17 Type: Once the letter ‘t’ is added, TI-Nspire CAS recognizes the input string as the name of the built-in function and does not display it in italics any longer. This feature helps avoiding s q r t name conflicts.
  • Page 18 This repeated the last example. Note that no expression was entered. If there is no expression in the entry line, TI-Nspire CAS uses the most recent entry. The keypad’s ‘Enter’-key shows the approximation symbol ≈ in blue color above the word ‘Enter’.

Therefore the answer appears cut off, as is indicated by the small black triangle just before the window’s right end.

There are also cases in which objects are partly dependent, such as a point on a line. The Geometry application allows you to move the independent objects and automatically all dependent objects are adjusted so that the properties that were enforced during the construc- tion (such as reflection, incidence, parallelism, etc.), are preserved.

By grabbing the line at a location different from the point that was used to draw it, you change the line’s direction. This results in a rotation of the line around the line’s defining point.
