Quiz 4 Instructions

The purpose of this quiz is to support your learning by
- offering you an opportunity to demonstrate your mastery of course material
- providing feedback so that you can plan your studying
- letting you see how your instructor writes quiz/exam questions, and grades them
- … in a low-stakes quiz, with plenty of time for you to make any needed adjustments before the first exam
This is a take home quiz:
- The quiz will become available at 6:00am on Sunday, September 20.
- The quiz must be completed by 6:00pm on Wednesday, September 23.
- The close time is strict.
The quiz is completed using a combination of WeBWorK and BlackBoard.
- The quiz questions are given in WeBWorK. Submit your answers in WeBWorK. You can use unlimited submissions, but you will not receive feedback on the correctness of the answers when submitted. (The purpose of multiple submissions is in case you find a mistake, or type your answer wrong.)
- In addition to answering the questions in WeBWorK, upload the written solutions to BlackBoard.
Solutions can be written by hand or using computer software, then create a .pdf document to upload.
- Handwritten: Write the solutions in easy to read hand writing, then scan the result using a tool like GeniusScan to create a single .pdf document.
- Annotation Software: Use annotation software to write up the solutions in easy to read writing. Then save the result as a flattened .pdf document.
- Typesetting Software: Use computer software such as LaTeX or Word+MathType to type up the solutions, then save the result as a .pdf document.
- Single PDF file submissions are strongly preferred, if possible. Please try to make your submissions (scanned work etc) combined into a single PDF if possible.
Quality of presentation of written work is a significant part of the grade. This includes:
- Neatness: Sloppy work will score poorly, if it gets graded at all.
- Organization: Work must be easy to find and easy to follow.
- Communication: Work must show how you reached your answer, and must make correct use of mathematical notation.
- Complete each question on a new page(s).
- You must show and explain your work. Use sentences. Your explanations have to make sense to a human being who is reading them.
- Please make sure that all of your scanned work is legible. That includes turning it to be oriented upright.
When working on the quiz students may:
- Discuss the questions with other students and/or the learning assistant.
- Ask their instructor for help.
- Use any of the course resources, notes, videos, etc. on the course website, or similar style resources.
- Use calculators or computers to do basic arithmetic.
When working on the quiz students may not:
- Ask any person to complete any part of the quiz for them.
- Copy another person’s work and present it as their own.
- Explicitly look up the solution to any problem online.
- Aid another student in any of the above activities.
- Commit any other infraction of the Student Code of Conduct.

Quiz 4 problems

This quiz has 5 questions.

You have to turn in your phase line graph. I don’t need to see your work on the rest of the problem.
Turn in your written work in solving this differential equation. For WeBWorK you will put in your final answer, and also one specific step of the work. Your written work (in BlackBoard) should show how you solved the equation.
This question has a few parts. Turn in the parts where you check that \(y_h\) is a solution of the homogeneous equation, and \(y_p+y_h\) is a solution of the nonhomogeneous equation. (The other parts, where you solve for \(A\) and \(y\), get entered into WeBWorK and I don’t need to see your work for them.)
Multiple choice question, don’t need to turn in written work.
Multiple choice question, don’t need to turn in written work.

(These are my, Zach’s, directions. Jaimos is using different directions for students in his section, collecting different written work.)
