Each problem has a reasonably short solution. If your calculation
gets completely out of hand, something must be wrong
(e.g., you might have chosen a wrong basis)
Grading policy *
I will take off a few (2-3) points for arithmetical mistakes. However,
a lot of points will be taken off for `obvious'
mistakes, i.e., either those that you can easily avoid or those
showing a deep misunderstanding of the subject. This includes, but
is not limited to, the following:
Wrong dimension in a physical problem
Things that don't make sense (like operations on matrices of incompatible
sizes, determinants of non-square matrices, etc.)
Inverse matrix with a row/column full of "0"s
An eigenvalue without eigenvectors
Furthermore, solving a different problem (other than stated), even if perfect,
will give you no credit
* Of course, this only applies to problems that I am grading personally
