Vector Notation
- A vector can be represented as A in bold, A underlined, or capital A, capital B with an arrow above
- Two or more vectors that have the same magnitude and direction are equal
- Vectors depend on how we get from the start to the finish rather than the location of those points
- Vectors with the same magnitude but opposite directions can be represented with the same letter but opposite signs
- When a vector points from B to A, we switch the letters round such that vector A, B becomes vector BA
- Vectors can also be expressed as column vectors, with the top number representing the x value and the second number representing the y value
