  • Book: Book: Differential Equations (Fourth Edition) Paul Blanchard, Robert L. Devaney and Glen R. Hall. BROOKS/COLE CENGAGE Learning
  • Download the software that is available with the text you may find it useful.

  • Objective: In this course you will rarely be asked to generate specific formulas for solutions of differential equations. Rather, you will be asked to understand the algorithms that lead to numerical solutions, to interpret the resulting pictures produced by the computer, and to relate these images back to the original application.

    Most students in the past have found this kind of course quite challenging, but lots of fun.

    The rapid pace of the class requires that you spend time every day doing homework, reviewing notes, reading the textbook, and working out extra problems, all in addition to the time spent in class.

  • Grading Policy:

  • Your grade will be determined as follows:

  • 50% two midterm exams (25% each)

  • 30% final exam

  • 20% quizzes

  • Important: There are NO makeup exams in this course.

    The midterm exams will be held on

  • Exam I: March 12, 2015 (Thursday)
