*: Recommended question. Not required if you know you can do it.
#: Make a graph.
0 z-component is 2
1 Use determinants.
2 Answer for a is wrong.
3 Use GE.
4 Use both methods.
5 Orthonormal matrix.
6 The value of b21 in the first column is 2, not 4. Be careful not to make errors in the determinant. Since u and v are nonunique, find those that result from Gram-Schmidt orthogonalization of the basis of the null space.
Also: Make exam 2 of 1998. Give yourself 50 minutes. Include your solutions with homework set Lin IV and grade yourself using the solutions on the web after you get it back.
