Math 402 Problem Set III 1. A coordinate system, v i , is defined as follows: v 1 = 2y -x -z v 2 = -x +y +z v 3 = 3z -y a) Find the contravariant transformation matrix, A . b) Find the covariant transformation matrix, B . c) Find the metric tensor for the v i system. d) Find the inverse of the metric tensor for the v i system. e) Find v^ i in terms of the x^ j . f) Find the u k vectors in the v i system in terms of v i and v^ j . g) Find the u n vectors in the v i system in terms of v i and v^ j . 2. In the v i system of problem 1 a "vector", G , is defined as follows: G = v 2 u 1 + 5 v 3 u 2 - v 1 u 3 . a) Find the contravariant components, G' k , of G in the v i system . b) Transform the G' k found in part a) to their "counterparts" in the x
