- Vector Calculus 1) Find the directional derivatives as a shown function of f at P (1,2,3) in the direction from P to Q (4,5,2) f(x, y, z) = x³y – yz² + zarrow_forwardM2arrow_forwardGreen's Second Identity Prove Green's Second Identity for scalar-valued functions u and v defined on a region D: (uv²v – vv²u) dV = || (uvv – vVu) •n dS. (Hint: Reverse the roles of u and v in Green's First Identity.)arrow_forward
- Explain “ some combination gives the zero vector, other than the trivial combination with every x=0.”arrow_forwarddouble check work plsarrow_forwardFlux of the radial field Consider the radial vector field F = ⟨ƒ, g, h⟩ = ⟨x, y, z⟩. Is the upward flux of the field greater across the hemisphere x2 + y2 + z2 = 1, for z ≥ 0, or across the paraboloid z = 1 - x2 - y2, for z ≥ 0?Note that the two surfaces have the same base in the xy-plane and the same high point (0, 0, 1). Use the explicit description for the hemisphere and a parametric description for the paraboloid.arrow_forward
