  • If you haven’t already, you can still work through this activity on the sine and cosine functions for an extra participation point. If you sign in using your free Desmos account, you should be able to save your work and return to it. Otherwise, you will have to complete the activity in one session.

Test #3 review part 1

Comment due Sunday, November 25

Test #2 will be given in class Wednesday, December 4. The format will be similar to the format of Test #1 and Test #2.

Recall from Test #1 and Test #2 that one of the questions asked you a series of conceptual true/false questions where you had to justify your answer. Another question asked you for a series of examples of mathematical objects (mostly functions) satisfying certain conditions.

To prepare for Test #3, for this week’s OpenLab assignment, you will comment on this post with two questions that you come up with yourself, as well as their answers.

  1. Your first question should be conceptual and phrased as a statement which is either always true or always false. Your answer should indicate whether the statement is true or false together with a sentence explaining the answer.
  2. Your second question should be asking for an example of a mathematical object satisfying certain conditions. Your answer should provide this example together with together with a sentence explaining the example and why it satisfies the conditions.

You can use the Test #1 and Test #2 questions for inspiration (the different versions of the tests had similar questions, so check out your classmates’ solutions here and here).

Try to focus on the material covered in class since Test #2. You can see the list of topics on the schedule.
