Basic Vectors

What is a vector?

  • Vectors represent a movement of a certain magnitude (size) in a given direction
  • You should have already come across vectors when translating functions of graphs
  • They appear in many contexts of maths including mechanics for modelling forces
  • Vectors can be represented in different ways such as a column vector or as an i and j unit vector

Examiner Tip

  • Think of vectors like a journey from one place to another.
  • Diagrams can help, if there isn’t one, draw one.
  • In your exam you can’t write in bold so should underline your vector notation.
