• Pressing = without inputting anything for
g(x) will generate a number

Note: • The maximum number of rows in the generated number table depends
on the setup menu table setting. Up to 30 rows are supported for the “f(x)”
setting, while 20 rows are supported for the “f(x),g(x)” setting. • You can
use the number table screen for viewing values only. Table contents cannot
be edited. • The number table generation operation causes the contents of
variable X to be changed.
Important: The function you input for number table generation is deleted
whenever you display the setup menu in the TABLE Mode and switch between
Natural Display and Linear Display.
Vector Calculations (VECTOR)
Use the VECTOR Mode to perform 2-dimensional and 3-dimensional vector
calculations. To perform a vector calculation, you first assign data to special
vector variables (VctA, VctB, VctC), and then use the variables in the
calculation as shown in the example below.
To assign (1, 2) to VctA and (3, 4) to VctB, and then perform the
following calculation: (1, 2) + (3, 4)
1. Press N8(VECTOR) to enter the VECTOR Mode.
2. Press 1(VctA)2(2).
• This will display the Vector Editor for input
of the 2-dimensional vector for VctA.
“A” stands for “VctA”.
