Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇f. (if the vector field is

gladu [14]

$\mathbf f$ is conservative if we can find a scalar function $f$ such that $\nabla f=\mathbf f$ . This is equivalent to solving the system of PDEs,

$\dfrac{\partial f}{\partial x}=2x-6y$

$\dfrac{\partial f}{\partial y}=-6x+10y-9$

Integrate both sides of the first PDF with respect to $x$ :

$f(x,y)=x^2-6xy+g(y)$

where $g$ is some function independent of $x$ . Then differentiatng with respect to $y$ , we have

$\dfrac{\partial f}{\partial y}=-6x+\dfrac{\mathrm dg}{\mathrm dy}=-6x+10y-9$

$\implies\dfrac{\mathrm dg}{\mathrm dy}=10y-9\implies g(y)=5y^2-9y+C$

and so $\mathbf f$ is indeed conservative, with

$f(x,y)=x^2-6xy+5y^2-9y+C$
