HL Matrix Transformations&Determinants (AHL3.9)
How do Matrices create transformations? What is the Geometric meaning of the Determinant?
On this page you can find a set of videos, created by James Tanton (training available here), for topics AHL 3.9 and 3.15 that provide a deep, conceptual insight into how/why matrices define transformations. An in-depth look at the geometrical meaning of a matrix's determinant and an introduction to Adjacency matrices are also provided.
Practice and Exam Style Questions follow at the bottom of this page (site membership is required for the exam style questions).
