To study for exam 2:
1.) If you can do all the review problems, you should be in good shape.
2.) If you have difficulty with factoring, check out Solving higher order linear homogeneous DE and the answers to quiz 4
3.) If you have difficulty with the LaPlace transform, check out Intro to Ch 6: LaPlace Transform. Note to perform the inverse transform requires only a few specific operations as described on page 2 of table of LaPlace transforms.
NOTE the (shorter) 6.2 problems are at the end of HW 9. Please make sure you do those before exam 2 even though they are at the end of the assignment. Since the 6.2 problems are shorter, you may want to do them first.
I forgot that 6.5 is covered on this HW. Since it is not on the exam, I have postponed the due date of HW 9 to THURSDAY (not Sunday), so you don't need to do the 6.5 HW problems until after Monday's exam 2. But if you would like extra practice, you can also do the 6.5 problems earlier.
4.) To see various different wordings for mechanical vibration problems, see Mechanical Vibration review.
To determine amplitude, period, frequency, and phase, convert to Rcos(wt - d).
Note (R, d) can be found by converting (c1, c2) to polar coordinates per Some review problems including answers. These old quiz problems with answers are also good review problems.
See MV slides for a review of damping (critical, under, over) as well as resonance, etc.
