Double integral with variable bounds, illustrating Fubini's theorem on non-rectangular domains
This program extends the iterated integral visualization to non-rectangular domains, where the inner integral has bounds that depend on the outer variable. The cross-sectional slices change in width as they sweep across the domain, and the boundary curves of the integration region are displayed alongside the surface. This is the generic form of Fubini’s theorem required for most practical double integrals.
