2. Press
(STO), and then perform one of the following key
operations to specify the copy destination:
(VctA),
(VctB), or
(VctC).
• This will display the Vector Editor with the contents of the copy
destination.
Vector Calculation Examples
The following examples use VctA = (1, 2) and VctB = (3, 4) from Example
1, and VctC = (2, -1, 2) from Example 2.
Example 3:
3 × VctA (Vector scalar multiplication), 3 × VctA - VctB
