Official public course description checked on 25 October 2026. Current section syllabus and weekly order have not been verified.
Across this collection: 140 distinct original families and 420 parameter instances. Courses share topic banks; translations and shared mappings are not extra questions.
Supported learning objectives
Linear systems
Solve small two-variable systems, count a free variable and identify a singular parameter.
Matrix calculations
Compute selected sum/product entries, 2×2 determinants and an inverse entry.
Euclidean vectors
Calculate dot products, lengths, distances and a projection coefficient in two or three dimensions.
What is not covered
Selected small-system, matrix-entry and Euclidean-vector calculations only. No full row-reduction workspace, abstract vector-space proofs, eigenvalues, diagonalization, complex arithmetic, cross products, or line/plane equation exercises.
An original worked example
Solve x+y=5 and x-y=-1. Enter x only.
Worked solution
Answer: 2
- 2x=4.
- Thus x=2 and y=3; both original equations hold.
