To edit the elements of a vector variable:
1. Press (VCT) (Edit), and then, on the menu that appears,
select the vector variable you want to edit.
2. Use the Vector Editor that appears to edit the elements of the vector.
• Use the and keys to display the element you want to edit.
Input a new value and then press .
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. You can input a vector variable
into a key operation by pressing (VCT) (Vct) and then pressing
one of the following number keys: (A), (B), (C).
Example 3: 3 × VctA = (3, 6) (Vector scalar multiplication), 3 × VctA - VctB
= (0, 2) (Calculation example using VctAns)
3 VctA
VctB
Example 4: VctA • VctB (Vector dot product)
VctA (VCT) (Dot) VctB
Example 5: VctA × VctB = (0, 0, -2) (Vector cross product)
VctA VctB
Example 6: Obtain the absolute values of VctC.
(Abs) VctC
Example 7: Determine the angle formed by VctA and VctB to three
decimal places (Fix 3). (Angle unit: Deg) (
, which
becomes )
