Vectors, matrices, transformations. The math behind ML, graphics, and everything else. No hand-waving. Just clear explanations with animations you can poke at.
Everything you need to actually understand linear algebra. Each module has interactive demos and quizzes.
What vectors actually are. Addition, scaling, and why vector spaces matter.
Multiplication, transpose, inverse. The operations you'll use constantly.
Rotation, scaling, shearing. See what matrices do geometrically.
That thing you memorized but never understood. Now with actual intuition.
Eigenvalues, eigenvectors. The key to PCA, PageRank, and quantum mechanics.
Gaussian elimination and beyond. Actually solve Ax = b.
Most linear algebra courses dump formulas on you without explaining what any of it means. That's backwards. This course starts with intuition and builds up to the formulas.
Every concept has an interactive visualization. Drag vectors around. Watch matrices transform grids. See the determinant change as you move things. That's how you build understanding.
