Problem 1
It requires matrix/vector structure, has interpretable evidence, permits validation, and is narrow enough to complete rigorously.
Faculty use
Reward correct mathematics, explicit dimensions/hypotheses, interpretation, and verification. Equivalent valid reasoning should receive credit.
It requires matrix/vector structure, has interpretable evidence, permits validation, and is narrow enough to complete rigorously.
Source, variables, units, cleaning, missingness, permissions, limitations, and transformations.
Definitions should identify the vector/matrix/space/transformation, dimensions or domain/codomain, and the hypotheses behind formulating a meaningful linear-algebra investigation with reproducible evidence. Use the formulas question → model → method → validation → limitation; variables and units documented.
A strong error analysis identifies the first step that violates a definition, dimension, theorem hypothesis, or matrix-operation rule; then repairs that step and re-verifies the final result.
Application responses vary. Require defined variables, a compatible matrix/vector model connected to large systems, reproducible computation, research communication, ethical data modelling, and advanced mathematics, a complete computation, interpretation, and limitations.
Accept two independent checks appropriate to the task: reconstruction, residual, RREF comparison, determinant/rank test, orthogonality, substitution, eigenpair check Av=λv, factorization product, or a second method.
