F is conservative if we can find a scalar funciton <em>f</em> such that grad(<em>f</em>) = F.
This would entail



Integrate both sides of the first equation with respect to <em>x</em> :

Differentiate both sides with respect to <em>y</em> :


Differentiate both sides with respect to <em>z</em> :


So we have

that satisfies

and so F is indeed conservative.
