Exam

• Final exam

  • The exam and the solutions.

    • Correction: The solution for problem 3: an extra factor of $\pi$ was erroneously kept in early parts---that piece of $\pi$ is now removed, throughout (thanks DH, CW, BS, and CM!)—1:07PM, Dec 16, 2014

  • Some example problems are listed here. (solutions)

    • Correction: The solution for 5(d): a missing $\cos \theta$ factor is put in (thanks, KD!).—10:38AM, Dec 14, 2014

    • Correction: The solution for problem 4(a) had a digital pad noise that caused the appearance of $\ddot l$ (thanks, EH, who pointed this out!). This is now fixed. There is no $\ddot l$. There is only $l$.—8:19PM, Dec 13, 2014

  • There will not be any review session for the final exam. But, here are some review materials.

  • On Friday, Dec 12, I will have open office hours from 9 AM through 2 PM. Also, you can use the online forum to discuss any challenging issues.
  • Two crib sheets of US letter size paper filled on both sides are allowed for the final exam.

• Midterm: The midterm on Nov 4 will cover materials up to Lecture note 9. However, materials in lecture notes 8 and 9 will be treated very lightly.

  • The exam and the solutions. The score distribution and the full grading rubrics are available here.

  • The review session is 3-5 PM on Nov 2, Sunday, in room PSB 114.

    • The audio recording and the photos of the blackboard are available for those of you who could not make it to the session.

  • Last year’s midterm should be reviewed. It should be regarded as a practice exam for this year. (However, you can ignore problem 2.) (solutions included)

  • Last year’s pre-exam can be reviewed as well. (solutions)

  • There will not be any quiz on this Thursday (Oct 30), nor will there be any new homework given out on that day. A new homework will be posted on Nov 4 and will be due Nov 13.
