Vector operations and the dot product

The questions ask you to say what a dot product measures in a situation, and to recognise one inside a constraint that never uses the word. The arithmetic returns quickly; noticing that a coefficient row applied to a point is the same operation is what needs practice.

What this covers

  • Compute with vectors and read the result geometrically

    Given vectors in R n , the learner can add and scale them, form a linear combination, and compute a dot product, saying what each result means geometrically.
