SOLUTIONS TO EXAMS I AND II

Textbook: W. Boyce and R. DiPrima; Elementary Differential Equations and Boundary Value Problems (Eight Edition) John Wiley and Sons, Inc.

About the course: We will study different kinds of differential equations and the methods used to solve them. We will cover : first order equations, second order linear equations (both homogeneous and non-homogeneous), power series solutions, systems of first order linear equations, some basic partial differential equations and methods used to solve them including Fourier series. (This will roughly be Chapters 2, 3, 5, 7, and 10 of Boyce and DiPrima.)

Clicking here Course Schedule you will get a detailed syllabus of the course. The syllabus is always subject to change according to the needs of the class.

Prerequisites:  MTH 243.

Policies: You are expected to abide by the University's civility policy:

"The University of Rhode Island is committed to developing and actively protecting a class environment in which respect must be shown to everyone in order to facilitate the expression, testing, understanding, and creation of a variety of ideas and opinions. Rude, sarcastic, obscene or disrespectful speech and disruptive behavior have a negative impact on everyone's learning and are considered unacceptable. The course instructor will have disruptive persons removed from the class."

Cell phones, IPods, beepers and any electronic device must be turned off in class.

You are required to do your own work unless specifically told otherwise by your instructor. In support of honest students, those discovered cheating on assignments or exams will receive a grade of zero on the assignment or exam. Use of unauthorized aids such as cheat sheets or information stored in calculator memories, will be considered cheating. The Mathematics Department and the University strongly promote academic integrity.

Grading Policy:

Your grade will be determined by your scores on

  • Exam I                                                                         : 100pts
  • Exam II                                                                        : 100pts
  • Final                                                                            : 150pts    (cumulative)
  • Quizzes and Homeworks and Maple Projects            : 150pts
  • Total                                                                            : 500pts
  • Homework: Homework will be assigned weekly but not collected or graded.  However the weekly quiz may be based on homework assignments.  If you do your weekly homework assignments you will have no problem with the exams.

    Quizzes: There will be weekly or biweekly quizzes.  The quiz will be given on Thursday.  I will drop the lowest quiz at the end of the term.

    There will be no make up quizzes or exams.

    Maple Projects: We will continue our work with Maple in this course. This powerful software is particularly useful in multivariable calculus to visualize graphs and surfaces in three dimensions.
