How to Calculate Vector Operations

What is Vector Operations?

Vector operations calculators handle 2D and 3D vector mathematics: addition, subtraction, scalar multiplication, dot product, cross product, and magnitude.

Formula

Cross product: a×b = (a₂b₃−a₃b₂, a₃b₁−a₁b₃, a₁b₂−a₂b₁)
b
(a₂b₃−a₃b₂ — (a₂b₃−a₃b₂

Step-by-Step Guide

  1. 1Addition: a + b = (a₁+b₁, a₂+b₂, a₃+b₃)
  2. 2Dot product: a·b = a₁b₁+a₂b₂+a₃b₃ (scalar)
  3. 3Cross product: a×b = (a₂b₃−a₃b₂, a₃b₁−a₁b₃, a₁b₂−a₂b₁)
  4. 4Magnitude: |a| = √(a₁²+a₂²+a₃²)

Worked Examples

Input
a=(3,1,−2) and b=(1,4,2)
Result
Dot product = 3+4−4 = 3; |a| = √14 ≈ 3.74
