Test #2 will be given next Thursday and Friday, November 5 and 6. The structure of Test #2 will be identical to that of Test #1. The interview sign-up sheet will be posted next week before the test.
Test #2 will cover Sections 5.1, 5.2, 5.3, 5.4, 5.6, and 5.7. You can see assigned textbook homework problems on the schedule here.
The structure of your Test #2 review assignment is also identical to that of the Test #1 Review assignment: choose one question (from WeBWorK or from the textbook) and post your solution on the OpenLab. Title your post “Test #2 Review” and add the section or WeBWorK set name and problem number. Add the category Test #2 Review before submitting your post. Due this Sunday, November 1.
Due on the OpenLab Sunday, November 1
The last question of the WeBWorK set 8-SecondOrderNonhomogeneous is the only WeBWorK question which corresponds with section 5.6. The WeBWorK set 9-SecondOrderVariationOfParameters, which corresponds to Section 5.7, has only two problems. To make sure you are seeing enough examples applying the techniques of reduction of order and variation of parameters, you will also choose one textbook homework problem to solve from these sections. You’ll share your solution on the OpenLab.
- Choose a question number from this list:
- 5.6 Reduction of order: p.253: 1, 2, 3, 5, 9, 13, 17, 19, 25, 31
- 5.7 Variation of parameters: p.262: 1, 2, 3, 4, 5, 7, 11, 13, 31, 33, 34
- Type your choice in the comments below (no more than two students per choice).
- Solve the problem and post your solution to the OpenLab. Title your post “Section [number] + question [number]” and select the appropriate category Second Order Reduction of Order or Second Order Variation of Parameters.
- After posts have been submitted, check someone else’s work and let them know your feedback in the comments on their post.
You will earn participation credit for completing this assignment.
