Announcements

    Whenever you view former tests, make it a habit to look here as well. On those occasions when a homework problem is assigned, I will post the solution here. Or if you hear any juicy rumors, such as "class has been canceled!", look here for confirmation.

The final exam will be given in room 109 on December 7, starting as early as noon. The exam consists of problems that employ only Lagrangian mechanics. In addition, you will be given optional problems that represent material covered on our previous four tests. By working these optional problems, you can add points to your previous test scores. The number of points you may add cannot raise your overall test score higher than 100. The maximum points you can add to previous test scores are:

Test 1   5 points
Test 2   8 points
Test 3   6 points
Test 4   3 points

The same page of integrals provided for Test 2 and the same formula sheet provided for Test 3 will be provided again.
