k
Using Math, Trig, and Advance Key Sets
The [Math1], [Math2], [Math3], [Trig] (trigonometric), and [Advance] key sets
contain keys for inputting numeric expressions.
The
L
key in the upper left corner and all of the keys in the bottom row are
common to all key sets. Their functions are described below.
L
Switches between template input and line input. See “Template Input
and Line Input” (page 24).
h
Performs the same operation as the keypad’s
K
key. Deletes the
character to the left of the current cursor position.
pq
See “Using the Clipboard for Copy and Paste” (page 21).
D
Inputs “ans”. See “Using the Answer Variable (ans)” (page 45).
w
Performs the same operation as the keypad’s
E
key, which executes calculations.
The keys in the following table are found on different key sets and are used to input functions and commands
for performing particular calculations and operations.
