Improper integrals are Calculus 2 limit problems in disguise. This Woody Calculus lesson teaches how to handle infinite intervals, vertical asymptotes, bad points inside an interval, p-integrals, comparison tests, convergence, and divergence with a clear step-by-step system.
Pointwise convergence checks one input at a time. Uniform convergence controls the whole domain at once. This Woody Calculus Real Analysis lesson explains the definitions, quantifiers, sup norm test, classic examples, and why uniform convergence preserves structure.
Gabriel’s Horn is one of the most unforgettable paradoxes in Calculus 2: a solid with finite volume but infinite surface area. Learn how the disk method gives volume π, while the surface area integral diverges using improper integrals and comparison.
