  • 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. Several of the projects due in this course will make extensive use of this software.

  • 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.

    You will also be required to perform projects and submit written reports. Your homework problems and questions on exams will often involve essays rather than simple routine computations. And you will often have to use technology to come up with answers to questions that are posed. Most students in the past have found this kind of course quite challenging, but lots of fun.

  • Grading Policy:

  • Your grade will be determined as follows:

  • 30% two midterm exams

  • 20% projects

  • 35% final exam

  • 15% homework

  • There will be three midterm exams in this course. However, we will drop your lowest score. Important: There are NO makeup exams in this course. If you miss an exam you will receive a zero for that exam and, presumably, you will wish to drop that score. Also, late project assignments will not be accepted. All projects must be handed in during (or before) the class on the day they are due.

    The midterm exams will be held on

  • Exam I: February 25th. (Tuesday)

  • Exam II: March 25th (Tuesday)

  • Exam III: April 22nd. (Tuesday)

  • I will announce later the date of the final exam. I want it to be a common exam for my two sections.

    Sections 1.5, 1.6, 1.8, 1.9 due Tuesday February 18th. at the beginning of the class. No late homework accepted!

  • Project Reports:

    Due Thursday March 6th. (at the beginning of the class). No late projects accepted! You can work in groups of 2 or 3 people, one report per group.

  • Accommodations: Any student with a documented disability is welcome to contact me as early in the semester as possible so that we may arrange reasonable accommodations. As part of this process, please be in touch with Disability Services for Students Office at 330 Memorial Union, 401-874-2098 (

    Illness due to flu: If any of us develop flu-like symptoms, we are being advised to stay home until the fever has subsided for 24 hours. So, if you exhibit such symptoms, please do not come to class. Notify me at 874-4451 or my email of your status, and we will work together to ensure that course instruction and work is completed for the semester.
    The Centers for Disease Control and Prevention have posted simple methods to avoid transmission of illness. These include: covering your mouth and nose with tissue when coughing or sneezing; frequent washing or sanitizing your hands; avoiding touching your eyes, nose, and mouth; and staying home when you are sick. For more information please view or . URI Health Services web page, , will carry advice and local updates.

    Standards of behavior: Students are responsible for being familiar with and adhering to the published "Community Standards of Behavior: University Policies and Regulations" which can be accessed in the University Student Handbook. If you must come in late, please do not disrupt the class. Please turn off all cell phones, pagers, or any electronic devices.
