Question

Consider a sheet S whose shape is given by the portion of the surface of equation z = 2 cos2 x + y (see figure), for which its density function is ρ (x, y, z) = x2 y + 1.

the figure is in the first attached image

The approximate mass of S corresponds to:

the answers are in the second image

A) M(S) = 6.7092
B) M(S) 5.7102
C) M(S) = 3.4286
D) M(S) = 5.1247
Transcribed Image Text:A) M(S) = 6.7092 B) M(S) 5.7102 C) M(S) = 3.4286 D) M(S) = 5.1247
S:z = 2 cos (x) + y
(y – 4)² = 8x
Transcribed Image Text:S:z = 2 cos (x) + y (y – 4)² = 8x
