Use the divergence theorem to calculate the surface integral s f · ds; that is, calculate the flux of f across s. f(x, y, z) = xyezi + xy2z3j − yezk, s is the surface of the box bounded by the coordinate plane and the planes x = 3, y = 6, and z = 1.

The Divergence Theorem, establishes that

∫∫S) F× dS = ∫∫∫v) (Div. F ) × dv

Solution is:

∫∫∫V) 2xyz³dx dy dz = 36

∫∫S) F× dS  = 36

We can either calculate   ∫∫S) F× dS or ∫∫∫v) (Div. F ) × dv wichever is easier

In order to answer that question we first find Div F.

Div F = ( δF/δx i + δF/δy j + δF/δz k ) × F

Div F = ( δF/δx i + δF/δy j + δF/δz k ) × ( xye∧z i + xy²z³ j - ye∧z k )

Div F = ye∧z + 2xyz³ - ye∧z

Div F = 2xyz³

In rectangular coordinates:   dv = dx×dy×dz Then

∫∫∫V) 2xyz³dx dy dz          Integration limits are :

x    from 0 to 3

y    from 0 to 6

z    from 0  to 1

∫∫∫V) 2xyz³dx dy dz = 2× ∫ ₀³x dx ∫₀⁶y dy ∫₀¹z³ dz

∫∫∫V) 2xyz³dx dy dz = 2 × x²/2 |₀³ × y²/2 |₀⁶ × (1/4) z⁴|₀¹

∫∫∫V) 2xyz³dx dy dz = 8 × 18 × (1/4)

∫∫∫V) 2xyz³dx dy dz = 36

has divergence

By the divergence theorem, the integral of across is equal to the integral of over the interior of :

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

i would say b) is your answer
