Matrices & Vectors

Matrices as transformations: multiply, invert, and find the directions they preserve.

  1. 01Matrix × VectorRows dot the vector, one output per row.+25
  2. 02Determinants (2×2)One number measuring area scaling — and invertibility.+25
  3. 03Solving with Cramer's RuleDeterminants solve a 2×2 system directly.+30
  4. 04EigenvaluesDirections the matrix only stretches, never rotates.+35
