37.2.5 Determinants and Area Scaling
Core ideaHow many times the transformation enlarges the area of a unit square is exactly the determinant det(A).
Module goal. Express direction and transformation with vectors and matrices, understand linear transformations, determinants, and solving systems of equations, and lay the groundwork for higher dimensions and abstract structures.
