Individual assignment—Test #2 cheat sheet

OpenLab post due Sunday, April 25

Test #2 will be given next Wednesday and Thursday. It covers Unit 2: Lessons 11 to 20 on the course hub and the corresponding Rederly WeBWorK sets. It will have the same format as Test #1.

For this week’s individual assignment, you will create a cheat sheet for Test #2 and share it on the OpenLab. Since Test #2 is open book and you are allowed to use your notes, you should think of this as a “theorem/definition/formula/example study sheet;” it’s not cheating to use it when you take the test!

It is up to you exactly what goes on your cheat sheet and how you organize it, but make sure it includes the statements of all of the series convergence tests, at the very least. You may include more detail and examples if you wish.

Submit a photo of your cheat sheet as an OpenLab post. Title your post Test #2 cheat sheet and select the category Week 12 individual post before publishing.

Group + individual OpenLab assignment: non-HOT-topic series test questions

Due Sunday, April 18

The instructions for this week’s group and individual assignment are similar to those for the Test #1 solutions: individuals will submit their own posts and the group secretary will link to them in the group post. Every individual who submits their own post and whose name appears on the group post will earn two participation points.

Motivation

Test #2 is coming up in Week 13 (you can see the week-by-week schedule here). This is a Test #2 review assignment. As in Test #1, you’ll have some questions that are similar to your HOT topic portfolio questions and you’ll have some other questions that are similar to the Rederly homework questions from Unit 2.

Before you meet with your group

Before you meet with your group, look through your questions on the following Rederly sets (even if you haven’t answered them):

  • Series – Taylor and Maclaurin Polynomials
  • Series – Infinite Series
  • Series – Infinite Series
  • Series – Integral Test
  • Series – Divergence Test
  • Series – Comparison Tests
  • Series – Alternating Series
  • Series – Ratio and Root Tests

(Note: there are two more sets in Unit 2 that will be covered on Test #2 but are not listed here.)

Look for questions that look fundamentally different from questions on your HOT topic portfolio. Fundamentally different means that the instructions for the question differ from those for HOT topic portfolio questions. Make a note of which questions you found.

When you meet with your group

  1. Discuss each of the questions that you found with your group (you do not have to solve them yet). Did any group members choose the same questions? Did any group member choose a question that is not fundamentally different from another group member’s HOT topic question? You may like to go back to your Rederly sets during your discussion to see more questions.
  2. As a group, from the list of your non-HOT topic questions, choose a question that each group member is responsible for. Make sure each group member’s question is fundamentally different from every other group member’s question.
  3. As a group, carefully answer the questions that you’ve chosen. This will probably take some serious discussion. Make sure every group member is comfortable with the solution that they are responsible for.

Individual post

Your individual post will include the text of the question and your complete solution for the question you are responsible for.

Title your post by the Rederly set name and the question number (so that other students can find the corresponding question in their own sets). Choose the category Week 11 individual post.

Group post

Once all the individual posts are posted, link to each of them. Include the group member’s name and the Rederly set name and question number.

Title the post Group n Week 11 group post (where n is your group number). Select the category Week 11 group post before publishing.

Week 10 group assignment: two bad convergence tests and one good one

Group Post due on the OpenLab Sunday, April 11

Motivation

This week’s group assignment is based on HOT Topics Standards 7 & 8:

  • Standard 7: Determine whether an infinite series converges absolutely, converges conditionally, or diverges
  • Standard 8: Determine whether an infinite series converges or diverges

It will be very straightforward for you to figure out which of your HOT Topics Portfolio questions align with Standards 7 & 8: just read the instructions for the questions carefully. It may not be straightforward to figure out how to answer them, however. You will have to use a convergence test to answer each question but depending on which series you have been assigned and which tests you’ve learned so far, it might be a test that you’re already familiar with or it might be a new one that you haven’t seen yet.
