47 Variables Overview
Automatic Sliders in Graphs
Sliders can be created for you automatically in the Graphs application and in the
analytic window of the Geometry application. You are offered automatic sliders when
you define certain functions, equations, or sequences that refer to undefined variables.
Linking a Lists & Spreadsheet Cell or Column to a Variable
When you link a cell or column to a variable, Lists &Spreadsheet updates the values to
reflect the current value of the variable. The variable can be any variable in the current
problem and can be defined in Graphs, Geometry, Calculator, or any instance of Lists
&Spreadsheet.
Notes:
• You cannot link to the same variable multiple times on the same page.
• Do not link a cell to a system variable. Doing so could prevent the variable from
being updated by the system. System variables include ans, StatMatrix, and
statistics results (such as RegEqn, dfError, and Resid).
Linking a Cell Value to an Existing Variable
1. In a Lists &Spreadsheet page, tap the cell that you want to link to a variable. This
should be an empty cell and the cell cannot be in a list that is already defined as a
variable.
2. Tap the cell again to open the context menu.
