Vectors in 3D Space

Explore vectors as arrows in 3D space. Adjust the components to see how they define direction and magnitude.

About Interactive Linear Algebra

An Interactive Visual Journey Through Linear Algebra

This tool helps you understand linear algebra concepts through interactive 3D visualizations.

Lessons:

  • Vectors in 3D: Understand vectors as directed quantities in space
  • Vector Addition: See how vectors combine using the parallelogram rule
  • Dot Product: Visualize projection and angles between vectors
  • Cross Product: Discover perpendicular vectors and area
  • Matrix Transformations: Watch how matrices transform space
  • Eigenvalues: Find special vectors that only scale
  • Basis Vectors: Build any vector from fundamental directions
  • Determinant: See how transformations scale area/volume

Controls:

  • Left Mouse: Rotate the view
  • Right Mouse: Pan the camera
  • Scroll: Zoom in/out
  • Sliders: Adjust vector components or matrix values
  • Play Button: Animate transformations (where available)

Tips:

  • Experiment with extreme values to build intuition
  • Watch how the coordinate grid transforms
  • Pay attention to the mathematical formulas
  • Try to predict what will happen before adjusting
