Vector Calculations - Casio fx-570EX User Manual

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: 12.
4. Perform the following key operation: (Define
Vector)(VctB)(2 dimensions).
5. Input the elements of VctB: 34.
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.
Vector Answer Memory
Whenever the result of a calculation executed in the Vector Mode is a
vector, the VctAns screen will appear with the result. The result also will be
assigned to a variable named "VctAns".
The VctAns variable can be used in calculations as described below.
• To insert the VctAns variable into a calculation, perform the following key
operation: (VctAns).
• Pressing any one of the following keys while the VctAns screen is
displayed will switch automatically to the calculation screen: , ,
, .
Assigning and Editing Vector Variable Data
To assign new data to a vector variable
1. Press (Define Vector), and then, on the menu that appears,
select the vector variable to which you want to assign data.
2. On the dialog box that appears, press  or  to specify the vector
dimension.
