Vector Calculations
Use the Vector app to perform two-dimensional and three-dimensional
vector calculations.
General Procedure for Performing a Vector
Calculation
To perform a vector calculation, use the special vector variables (VctA,
VctB, VctC, VctD) as shown in the example below.
Example 1: To calculate (1, 2) + (3, 4)
•
When performing addition or subtraction of two vectors, they both must
have the same dimensions.
1. Press , select the Vector app icon, and then press .
•
This displays the vector calculation screen.
2. Press .
•
This displays the vector variable list screen.
