Web17 de jan. de 2024 · OpenStax Learning Objectives Recognize when a function of two variables is integrable over a general region. Evaluate a double integral by computing an iterated integral over a region bounded by two vertical lines and two functions of x , or two horizontal lines and two functions of y. Web7 de mar. de 2024 · A cup would not be closed, because it's open on the top. "Bounded" means there is some sphere with finite radius that completely encloses the surface. Both of these surfaces would be bounded; unless the balloon/cup is infinitely large, there is some sphere that contains them.
