6. Press to generate the number table.
Press to return to the screen in
step 3.
Tip
In the number table shown in step 6, you can change the value in the
currently highlighted x cell. Changing the x value causes the f(x) and g(x)
values in the same line to be updated accordingly.
If there is value in the x cell above the currently highlighted x cell,
pressing or automatically inputs into the highlighted cell the
value equal to the value of the cell above it plus the step value. So also,
pressing automatically inputs the value equal to the value of the cell
above less the step value. The f(x) and g(x) values in the same line are
also updated accordingly.
Note
After pressing in step 4 above, proceeding from step 5 onwards
without inputting anything for g(x) will generate a number table for f(x)
only.
The maximum number of rows in the generated number table depends
on the setup menu table setting. Up to 45 rows are supported for the
f(x)” setting, while 30 rows are supported for the “f(x),g(x)” setting.
The number table generation operation causes the contents of variable x
to be changed.
Important: Functions input in this mode are deleted whenever the Input/
Output settings are changed in the Table Mode.
Vector Calculations
Use the Vector Mode to perform 2-dimensional and 3-dimensional vector
calculations. To perform a vector calculation, use the special vector
variables (VctA, VctB, VctC, VctD) as shown in the example below.
Example: (1, 2) + (3, 4)
1. Press , select the Vector Mode icon, and then press .
2. Press (VctA)(2 dimensions).
This will display the Vector Editor for
input of the 2-dimensional vector for
VctA.
3. Input the elements of VctA: 12.
4. Perform the following key operation: (Define
Vector)(VctB)(2 dimensions).
5. Input the elements of VctB: 34.
6. Press to advance to the calculation screen, and perform the
calculation (VctA + VctB): (VctA)(VctB).
This will display the VctAns (Vector
Answer Memory) screen with the
calculation results.
