Study Tips

  1. Master the definitions: Linear algebra requires precise understanding of vector spaces and linear maps
  2. Practise proofs: Learn to write clear, rigorous proofs
  3. Draw diagrams: Visualise vector spaces, transformations, and decompositions
  4. Learn standard examples: Know the properties of common matrices (diagonal, symmetric, orthogonal)
  5. Connect to applications: Relate linear algebra to data science, physics, and engineering
