Foundations for undergraduate mathematics
Theory written with the structure and rigor of upper-division courses, made accessible to undergraduates. Paired with step-by-step computation, interactive 3D visualization, and adaptive practice across calculus, linear algebra, and beyond.
Vector spaces, linear maps, eigenvalues, inner products, and the spectral theorem.
Vector Spaces · Matrices · Determinants · Eigenvalues · Inner Products
Topology, manifolds, vector fields, and the integral theorems of Green, Stokes, and Gauss.
Topology · Manifolds · Jacobian · Vector Fields · Stokes · Divergence
Adaptive practice that adjusts to your level with instant feedback, progression tracking, and timed modes.
Derivatives · Integrals · Limits · Series · Taylor · Linear Algebra · ODEs
Step-by-step symbolic computation with a 3D function plotter for derivatives, integrals, eigenvalues, and more.
Graphing · Derivatives · Integrals · Eigenvalues · Determinant · QR
Choose topics from Calculus 1 & 2, Linear Algebra, or Multivariable Calculus. Study condensed notes and worked examples, then take a timed exam. The engine weights questions toward your weakest areas and tracks mastery over time.
