Problem 1- Apply the operator ∇ to products of smooth scalar fields Φ, Ψ, vector fields u, v, and tensor fields A, B. Establish the identities

div(Φu) = Φdivu + (u, gradΦ)

grad(u, v) = (gradTu)v + (gradTv)u

div(ATu) = (divA,u) + A : gradu

Problem 2- Compute the derivate DG(A) for each of the following functions

G(A) = (trA)A

G(A) = ABA

G(A) = ATA

G(A) = (u, Au)A
