Extra Notes
Midterm, Nov 5: First page. No cribsheet is allowed in the exam: only pens, pencils and erasers are allowed. No calculator allowed. This pdf file is only for your (p)review before the exam and a print-out of it should not be brought to the exam. This page will be the first page of the exam, and thus will be provided at the exam.
Correction: : (20) sign of a term in $\sigma_z$. Thanks, L! – 6:25PM, Nov 05, 2012
