📖How to Use
- 1Enter vector components (2D or 3D)
- 2Select an operation (addition, dot product, cross product, magnitude, angle)
- 3See the result and its geometric meaning
💡Tips & Knowledge
- •Dot product: a·b = |a||b|cosθ. If two vectors are perpendicular, their dot product is 0
- •Cross product is 3D only. The result is a vector perpendicular to both input vectors
- •The magnitude of the cross product equals the area of the parallelogram formed by the two vectors
