Obtain the absolute value of each element of MatB (Abs(MatB)).
@(Abs) MatB
Determine the square and cube of MatA (MatA

).
Note: You cannot use for this input. Use 7 to specify squaring, and
7(
x
3
) to specify cubing.

Creating a Number Table from a
Function (TABLE)
TABLE generates a number table for x and f(x) using an input f(x) function.
Perform the following steps to generate a number table.
1. Press (TABLE) to enter the TABLE Mode.
2. Input a function in the format
f(x), using the X variable.
• Be sure to input the X variable (
(X)) when generating a number
table. Any variable other than X is handled as a constant.
•
The following cannot be used in the function: Pol, Rec, °,
d/dx, 3.
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
while the number table screen is displayed will return to
the function input screen in step 2.
