Determine if the binary relation <= is a partial order on A
in the following cases:
(a) A = N × N and (a1, b1) (a2, b2) ⇔ a1 <= a2 for (a1,
b1),(a2, b2) ∈ A
(b) X = {1, 2, 3, 4}, A = P(X) and a <= b ⇔ #a <= #b for
a, b ∈ A (Here #a denotes the number of elements in the set a)
(c) A = N and a <= b ⇔...

For each of the following vector fields F, decide whether it is
conservative or not by computing curl F. Type in a potential
function f (that is, ∇f=F). Assume the potential function has a
value of zero at the origin. If the vector field is not
conservative, type N.
A. F(x,y)=(−14x−6y)i+(−6x+6y)j
f(x,y)=
C. F(x,y,z)=−7xi−6yj+k
f(x,y,z)=
D. F(x,y)=(−7siny)i+(−12y−7xcosy)j
f(x,y)=
E. F(x,y,z)=−7x^2i−6y^2j+3z^2k
f(x,y,z)=
