• Be sure to input the X variable (

S)(X)) when generating a number

table. Any variable other than X is handled as a constant.

• If you are using a single function, input a function in the format

f

(

x

)

only.

• The following cannot be used in the function: Pol, Rec,

∫,

d/dx

,

Σ, Π.

3. In response to the prompts that appear, input the values you want to use,

pressing

= after each one.

For this prompt: Input this:

Start?

Input the lower limit of X (Default = 1).

End?

Input the upper limit of X (Default = 5).
Note: Make sure that the End value is always
greater than the Start value.

Step?

Input the increment step (Default = 1).
Note: The Step specifies by how much the Start
value should be sequentially incremented as the
number table is generated. If you specify Start = 1
and Step = 1, X sequentially will be assigned the
values 1, 2, 3, 4, and so on to generate the number
table until the End value is reached.

• Inputting the Step value and pressing

= generates and displays the

number table in accordance with the parameters you specified.

• Pressing

A while the number table screen is displayed will return to

the function input screen in step 2.
