FNH 250 Chapter 2: Ch. 2

For each of the following vector fields FF, decide whether it is conservative or not by computing curl FF. Type in a potential function ff (that is, ∇f=F∇f=F). Assume the potential function has a value of zero at the origin. If the vector field is not conservative, type N.

F(x,y,z)=6xi+7yj+k
f(x,y,z)=f(x,y,z)=
