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)=
