Homework

• Homework set 5, due Nov. 1. Due date changed. However, honing your skills on the Lagragian mechanics will prepare you well for the midterm. Very basic Lagrangian problems will feature in the midterm (see the practice exam). No Hamiltonian (or effective potential defined through Hamiltonian) will be in the midterm, though.

• Homework set 4, due Oct. 20. (solutions).

  • Problem 2: added the info that $a > 0$ is a constant too.

• Homework set 3, due Oct. 13 (solutions).

  • Grade stats: 31 ± 11 out of 50, max 49, min 4.

  • Problem 6: n = integer → n = non-zero integer.

  • Problem 5(a): "stable" added.  5(b): "Show" → "Prove" and "indeed" added.

• Homework set 2, due Oct. 6 (solutions).

  • Grade stats: 32 ± 14 out of 60, max 60, min 10.

  • Correction: sols, 1(a), line 3 of solution, at end: $\left(\begin{smallmatrix} 1\\ 0\\ 0 \end{smallmatrix}\right) \rightarrow \left(\begin{smallmatrix} 0\\ 0\\ 1 \end{smallmatrix}\right)$. — Sam, 4:49PM, Oct 10, 2011

  • Due date corrected (Thursday). One clause added to 3(c) ("that does not involve t").

• Homework set 1, due Sept. 29 (solutions).

  • Grade stats: 44 ± 5.3 out of 50, max 50, min 25.

  • Page 2: figure positions fixed. — Sam, 4:40PM, Oct 03, 2011

  • Problem 4 removed (will reappear in HW 2). — Sam, 4:24PM, Sep 22, 2011
