You can also use it to define variables, functions, and programs. When you define or edit a variable, function, or program, it becomes available to any TI-NspireTM math and science learning technology application--such as Graphs & Geometry--that resides in the same problem. You can also use Calculator to define library objects, such as variables, functions, and programs, which are accessible from any problem of any document. For information on creating library objects, see the "Libraries" section of the documentation. Calculator menu This menu is available anytime you are in the Calculator work area. The menu in this screen snapshot may not exactly match the menu on your screen. Calculator work area You enter a math expression on the entry line and then press to evaluate the expression. Expressions display in standard mathematical notation as you enter them. 55 Using Calculator Entered expressions and results show in the Calculator history. Example of Calculator variables used in another TI-NspireTM application The Calculator tool menu The Calculator tool menu lets you enter and evaluate a variety of math expressions. Menu Name Menu Option Function Actions Define Recall Definition Inserts the Define command. Lets you view, reuse, or modify a function or program that you have defined. Deletes all variables with single-letter names. Deletes all expressions in the Calculator history. Lets you refresh all libraries, set LibPub or LibPriv access, or insert a "\" character Delete Variable Clear a-z Clear History Insert Comment Library Number Convert to Decimal Factor Least Common Multiple Greatest Common Divisor Remainder Fraction Tools Inserts Decimal command. Lets you select propFrac(), getNum(), getDenom(). 56 Using Calculator Menu Name Menu Option Number Tools Function Lets you select round(), iPart(), fPart(), sign(), mod(), floor(), or ceiling().

Lets you select rand(), randInt(), randBin(), randNorm(), randSamp(), or RandSeed. 57 Using Calculator Menu Name Menu Option Distributions Function Lets you select from several distributions, such as Normal Pdf, Binomial Cdf, and Inverse F. Statistics Stat Calculations Lets you select from several statistics calculations, such as one-variable analysis, twovariable analysis, and regressions. [. . . ] Remember that TI-Nspire computer software is case insensitive: RUN0. TEMP_C and run0. temp_c reference the same set of data. 126 Data Collection Storing collected data To save the current data before rerunning an experiment, use the following instructions. To save temperature data 1. Cut and paste each column of data into new columns. The first two columns (Columns A and B) will be reused by the next run of the experiment. Rename each moved column. 2. Repeat the steps for each data sample you want to save. [. . . ]
