A general finite rotation by an angle Φ about the axis with unit normal n, (n_k n_k = 1), is described by ¯xi = A_ij x_j where the components of the matrix A_ij are given
A_ij = cos Φ δ_ij + (1 − cos Φ) n_i n_j + sin Φ ε_ijk n_k.
Evaluate A_ij A_iℓ explicitly to show that A_ij A_iℓ = δ_jℓ

By "transforming the same way" we mean that V DV where D is the same matrix as appears in Dr. In particular for a rotation about the z axis we should have cos p-sinp0 sincos 0 0 where φ is the angle of rotation.

z-axis is (a 2D rotation):
Where
is the angle to rotate. Then rotation from A to A' is can be
represented via matrix multiplications: [A'] = [R][A]
Such a rotation is useful to return a system solved in
simplified co-ordinates to it's original co-ordinate system,
returning to original meaning to the answer. A full 3D rotation is
