Test #1 will be given in class on Tuesday, September 20. The test has 5 questions; you will answer all 5. All questions are based on material from Chapter 2 (everything we’ve seen so far in class). Make sure you indicate which method you are using and show all your work for each question. Your work may earn partial credit.

For linear first order equations, the method of integrating factors will earn zero credit; use variation of parameters instead (see Section 2.1 of the textbook, not Lesson 2 from the course hub).

You are allowed to bring a cheat sheet with you:

  • one side of one letter-sized sheet of paper (notebook paper is fine)
  • hand written by you
  • you will hand your cheat sheet in with your test (put your name at the top)
