![]() ![]() Find the volume of the solid that lies under z f x, y x2 C y2 and above the region D which is the region bounded the parabolas y 2 x and y x2. Volume of the solid bounded the elliptic paraboloid x2 C 2 y2 C z 16, the planes x 2, y 2, three coordinate planes. a) 0 2 3 b) 1 x2 y dy dx 1 x2 y dx dy 0 Theorem If f is continuous on the rectangle R b d f x, y dA d b f x, y dy dx a c x, y a x b, c y d then f x, y dx dy c a R SO! If the function is nice enough to be continuous double integral is interated integral and it is easy just like Cal I. Using Geometry x, y K1 x 1, K2 y 2, 1 Kx2 D A R Section 12 Iterated Integrals 3 2 e. Divide R into four equal squares and choose the sample point to be the upper right corner of each square Rij. Use double Riemann sum tp estimate a volume of the solid that lies above the square R 0, 2 0, 2 and below the elliptic paraboloid z 16 Kx2 K2 y2.
