Uses of eigenvalues, particularly in dynamic systems. Revisits Markov chains. Using matrix powers, the long-term behavior of the system is analyzed through the steady-state vector.

Focuses on practical uses of eigenvalues and eigenvectors, particularly in modeling systems over time. Diagonalization and introduces Markov chains, using transition matrices to model population. Discusses concept of a steady-state vector representing long-term equilibrium.

Expands on diagonalization and introduces complex eigenvalues. It reviews conditions under which a matrix is diagonalizable. Discusses the Fundamental Theorem of Algebra. Defines complex numbers, their conjugates, and modulus, and explains complex conjugate pairs.

Introduces the concepts of eigenvalues and eigenvectors, how a matrix transforms vectors by stretching or reversing their direction. Explains how that eigenvectors are found. Also covers diagonalization. It includes conditions for diagonalizability and shows how the eigenvalues of a diagonal matrix are just its diagonal entries.

Focuses on expressing linear transformations as matrix operations. Covers how to find matrices for transformations like rotations and reflections. Includes the kernel and the image. Explains how to compute transformation matrices and find bases for the kernel and image through row reduction.

Introduces subspaces, bases, dimension, null space, column space, and row space. Explains how to find bases using row reduction, defines rank and nullity, and presents the Rank-Nullity Theorem. Shows how to determine if vectors form a basis and interpret matrices as linear transformations.
