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
Elis [28]

In order for <em>F</em> to be conservative, there must be a scalar function <em>f</em> such that the gradient of <em>f</em> is equal to <em>F</em>. This means

\dfrac{\partial f}{\partial x}=3x^2-2y^2

\dfrac{\partial f}{\partial y}=4xy+4

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

f(x,y)=x^3-2xy^2+g(y)

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

\dfrac{\partial f}{\partial y}=-4xy+\dfrac{\mathrm dg}{\mathrm dy}=4xy+4\implies\dfrac{\mathrm dg}{\mathrm dy}=8xy+4

But we assume <em>g</em> is a function of <em>y</em>, which means its derivative can't possibly contain <em>x</em>, so there is no scalar function <em>f</em> whose gradient is <em>F</em>. Therefore <em>F</em> is not conservative.

Reflect the point (-20,4)
Firdavs [7]
Refrection of (-20, 4) across x-axis gives (-20, 4) = (-20, -4)

Refrection of (-20, 4) across y-axis gives (20, 4)

Refrection of (-20, 4) across y = -x gives (20, -4)

Refrection of (-20, 4) across y = 7 gives (20, 10)
