Answer:
2.794
Step-by-step explanation:
Recall that if G(x,y) is a parametrization of the surface S and F and G are smooth enough then
F can be written as
F(x,y,z) = (xy, yz, zx)
and S has a straightforward parametrization as
with 0≤ x≤1 and 0≤ y≤1
So
we also have
and so
we just have then to compute a double integral of a polynomial on the unit square 0≤ x≤1 and 0≤ y≤1
=1/3+2-2/9-2/5+3/2-1/4-1/6 = 2.794
Adding 49 will explain it properly just do that and you will get the answers
For the first one the answer is x = -3/2y - 7 and the second answer is x = 1/6y + -11/3
