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
(Calculation example using VctAns)
3 (VECTOR) (VctA)
(VECTOR) (VctB)
Example 4: VctA • VctB (Vector dot product)
(VECTOR) (VctA)
(VECTOR) (Dot)
(VECTOR) (VctB)
Example 5: VctA × VctB (Vector cross product)
(VECTOR)
(VctA)
(VECTOR) (VctB)
Example 6: Obtain the absolute values of VctC.
(Abs)
(VECTOR) (VctC)
Example 7: Determine the angle formed by VctA and VctB to three
decimal places (Fix 3). (Angle unit: Deg)
(cosθ =
(A∙B)
|A||B|
, which becomes θ = cos
-1
(A∙B)
|A||B|
)
