• Adding, Subtracting and Scaling Vectors

  How to add vectors end to end and by components, why the length of a sum is usually less than the sum of the lengths, how subtraction works, and what scaling does.

• The Dot Product and the Angle Between Vectors

  Multiply two vectors into a number: u · v = u₁v₁ + u₂v₂ equals |u||v|cos θ, which measures the angle between them, tests for right angles and gives projections.
