Students begin by exploring vectors as mathematical quantities that possess both magnitude and direction. They distinguish vectors from scalars, represent vectors graphically and algebraically, resolve vectors into components, and perform vector operations. The unit concludes by applying vectors to displacement, velocity, force, and navigation problems, establishing the foundations for vector geometry.
This unit expands students' understanding of vectors by introducing the dot product, cross product, and vector equations of lines and planes. Students investigate geometric relationships in two and three dimensions, calculate angles and projections, analyse intersections, and use vectors to model transformations and physical systems. Emphasis is placed on interpreting vector methods both algebraically and geometrically.
Students are introduced to matrices as efficient tools for organising information and solving mathematical problems. They investigate matrix notation, perform matrix operations, calculate determinants and inverses, and use matrices to solve systems of linear equations. Throughout the unit, students explore the relationship between matrix methods and traditional algebraic techniques.
In this unit, students investigate how matrices describe geometric transformations and model complex systems. They apply transformation matrices to rotations, reflections, enlargements, and shears while exploring eigenvalues, eigenvectors, and transition matrices. Practical applications include computer graphics, robotics, engineering, scientific modelling, and technological systems.
The final unit integrates vectors and matrices with broader areas of mathematics and technology. Students investigate vector-valued functions, introductory linear algebra concepts, optimisation, and applications in machine learning, artificial intelligence, and data science. The course concludes by synthesising vector and matrix techniques to solve authentic, multi-step mathematical problems.
