kUsing the 2D Keyboard

The 2D keyboard provides you with a number of templates that let you input fractions, exponential values, nth roots, matrices, differentials, integrals, and other complex expressions as they appear in your textbook.

It also includes a Vkey set that you can use to input single-character variables like the ones you can input with the math (mth) keyboard.

uInitial 2D keyboard key set

This key set lets you input fractions, exponential values, nth roots, etc. as they appear in your textbook.

Tip

• For information about each function or symbol, see “2-4 Function Calculations”.

u - key set

Tapping the - key displays a keyboard like the one shown below, which has a Ikey in place of the - key. Tapping Ireturns to the initial 2D keyboard.

The following are the mathematical expressions you can input with this 2D keyboard.

To input this:
