Info on the Quizzes is posted here. There will be six quizzes. Each quiz is worth 20 points. The lowest quiz score will be dropped. You will be given 25 minutes of class time to complete each quiz. Calculators will not be allowed on the quizzes.

• Date: June 21st
• Material covered
  • § 2.1: integrating factors
  • § 2.2: separable equations
• Problems from your book which are similar to those on the quiz
  • § 2.1 #13, 14, 15
  • § 2.2 #10 (skip part (b))
• CALCULUS REVIEW MATERIALS (from a previous 307 class taught by Don Marshall)
  • Formulae
  • Problems (this is a pdf from a previous class so ignore everything but the problems; in particular, you will not be explicitly tested on this material.)
  • The problem book on calculus in the Schaum's Outlines series is also good for review
• Results: Average: 13.5 ; Median: 15 ; High Score: 19
• Comments
  • Problem 1: Many tried to do integration by parts; a u-sub, u=-t^2, is the correct way to compute the integral. Also, e to the negative t squared times e to the t squared is 1 not zero.
  • Problem 2: Most people got full credit on part a. For part b, always remember to check that the endpoints of the interval make sense in the differential equation, in this case they don't and we can't include them.
