Divergence Theorem Explained: Flux, Closed Surfaces, and a Complete Example

The Divergence Theorem converts outward flux through a closed surface into a triple integral of divergence over the enclosed solid. Learn the theorem’s conditions, flux and divergence meanings, method-selection rules, singularity warnings, and a complete sphere example with exact verification.

Line Integrals and Vector Fields: What They Measure in Calculus 3

Line integrals are one of the core ideas in Calculus 3 and vector calculus. Learn what line integrals measure, how vector fields interact with paths, why direction matters, and when different paths from the same start to the same end can produce different work.
