General Menu

The following page describes the less obvious buttons on the general menu.

{ }

These buttons are used to designate lists and also for grouping data for statistics. See the links for more information.

Exec

Inserts appropriate number of prior entries on the stack into a formula which must be the last entry on the stack. For instance, if the stack contains the following entries:

    3, 4, 3x + y

The result will be 13 (the evaluation of 3*3 + 4).

This operation becomes more powerful when combined with the use of lists. For instance if the stack contains the following:

    {1, 2, 3, 4}, x² + 2x

The result of this operation will be the following list:

    {3, 8, 15, 24}

Graph

Executes the Graphing function.

x

Shortcut key for entering an x variable in a function. The user may use the keyboard to enter any letter or combination of letters desired for a variable, but this key provides a shortcut for the most common variable name when using the app on a tablet.
