Vector Calculations (VCT) (fx-570MS/
fx-991MS only)
Use the
key to enter the VCT Mode when you want to perform
vector calculations.
(VCT)
Use the VCT 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.
Example 1: To assign (1, 2) to VctA and (3, 4) to VctB, and then perform
the following calculation: (1, 2) + (3, 4)
1. Press
(VCT) (Dim) (A).
2. Input the dimensions of VctA: 2 .
•
This will display the Vector Editor for input of the 2-dimensional vector
for VctA.
(1) Dimensions of vector
(2) Arrow indicates direction you should scroll to view other elements.
3. Input the elements of VctA: 1 2 .
