Vectors
Akopọ
A delivery drone needs more than a distance to reach its target: it needs a direction too. Fly 4 km the wrong way and you are further from the parcel than when you started. Vectors are the tool mathematics uses to carry size and direction together, and they turn awkward geometry problems, where a diagram only gets you so far, into clean algebra.
This topic builds vector notation and column vectors from the ground up, covers addition, subtraction, scalar multiplication and magnitude, and finishes with the technique examiners favour most at Higher tier: using vectors to prove that lines are parallel, that points are collinear, and that several lines meet at a single point.
Awọn Afojusun
- Understand scalar and vector quantities in two dimensions
- Understand and use vector notation including column vectors
- Represent a vector by a directed line segment
- Understand and use parallel vectors, unit vectors and position vectors
- Find the sum and difference of two vectors
- Calculate the modulus (magnitude) of a vector
- Multiply a vector by a scalar
- Find the resultant of two or more vectors
- Apply vector methods to simple geometrical problems including collinearity, parallel lines and concurrency
