Assignment #13 (Due Wednesday, 4/4/07)
Posted: Sun Apr 1 19:37:03 MDT 2007
Clarified?: Mon Apr 2 14:01:28 MDT 2007

All three of these via Laplace transforms:

• 5.2: 21, 22
• Problem 3 on the sheet reached by clicking here.

Notes:

1. Recognize and use partial fractions (rather than items 5 and 6 in the back-endpaper list).
2. For each of the three problems, write a "Step-free" solution formula. See equation (11) on page 310 for an example of this.

Remove 5.2: 18 from Assignment #12
Posted: Thu Mar 22 15:06:16 MST 2007

It has been pointed out to me that 5.2: 18 needs to use entries 14 and 15 in the end-paper Laplace-transform table in the text.

So, let's remove 5.2: 18 from Assignment #12 until after April-Fool's Day...

Assignment #12 (Due Friday, 3/23/07)
Posted: Mon Mar 19 17:50:36 MST 2007

• Get familiar with the Laplace-transform table in Diary3.
• 5.1: 29, 30, 31 (should be do-able without reference materials)
• 5.2: 8, 10, 11, 17, 18

Not to hand in, but recommended: at least the underlined ones 5.1: 1-32. Also the underlined 5.2: 1-22.
