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 )

• ･････(Fix) VctA (VCT)(Dot) VctB
  (Abs) VctA (Abs) VctB
