The determinant | Chapter 6, Essence of linear algebra
Determinants turn the messy question of “how much does a linear transformation stretch space?” into a single number: the factor by which areas (in...
Cross products | Chapter 10, Essence of linear algebra
Cross products turn the geometry of a parallelogram into an algebraic object: in 2D, they produce a signed area, and in 3D, they produce a...
Complex Analysis 26 | Keyhole contour
A keyhole contour integral around an isolated singularity collapses to a simple statement: for a function holomorphic on a punctured disk, the...
Linear Algebra 43 | Determinant (Overview)
Determinants are introduced as a square-matrix concept that turns geometric information into a single real number—one that signals whether a matrix...
Manifolds 48 | Stokes's Theorem as the Fundamental Theorem of Calculus
Stokes’s theorem emerges as a “fundamental theorem of calculus” for manifolds once orientation is handled correctly—down to the zero-dimensional...
Manifolds 47 | Tangent Space and Orientation on the Boundary
A manifold’s boundary needs its own tangent-space and orientation conventions—because Stokes’ theorem links integrals over a manifold to integrals...
