Introduction to Differential Equations (MATH 334 - A1)

Fall Term 2017 (Class Dates: 5-Sep-2017 to 8-Dec-2017)

Instructor: Professor Hao Wang, Department of Mathematical & Statistical Sciences, CAB 539.


LECTURE TIME & LOCATION: 12:00-12:50pm on Monday, Wednesday & Friday in SAB 325.

OFFICE HOURS: 1:00-3:00pm on Monday & 1:00-2:00pm on Friday (or else by appointment).

TEXTBOOK: Elementary Differential Equations and Boundary Value Problems (10th Edition) by Boyce and DiPrima.

COURSE CONTENTS: Chapters 1-6 in the textbook.


EXAMINATION POLICY: The midterm exam will be in class on October 23 (Monday)If a student has an acceptable excuse for missing the midterm exam, the weight of the midterm exam will be transferred to the final exam. There will be no deferred midterm exam.

The final exam is cumulative and will be given in SAB 325 at 2:00-4:00PM on December 20, Wednesday. For those eligible, the deferred final exam is arranged through your Faculty Office. The deferred final exam will be written on Saturday January 13th 2018. Registration for the exam will be at 8:30 am outside CAB 357, and the exams will begin at 9:00 am. Warning: It is your responsibility to confirm all the details associated with the time and location of the deferred final exam. I play no role in determining any aspect of these particular details. It is official University policy that failure to know where and when a deferred exam is to be held is not an acceptable excuse for missing it (i.e., a non-appealable final-exam grade of zero will be assigned).

Your student photo I.D. is required at exams to verify your identity. Students will not be allowed to begin an examination after it has been in progress for 30 minutes. Students must remain in the exam room until at least 30 minutes has elapsed. Electronic equipment cannot be brought into examination rooms.


HOMEWORK ASSIGNMENTS: The assignment problems will be posted in class and on my MATH 334 website. The completed assignments must be placed in the "assignment box" on the 3rd floor in CAB with my name on it by 4:00pm on the due date. Late assignments will not be marked and a grade of zero will be assigned. While I mark the Exams and assign your final grade, I do not mark the Assignments. These are done by a teaching assistant. However, should you have any issue to discuss about the assignments, please come to see me.

ABSENCES: If you cannot submit an assignment for a valid reason, please inform your course instructor before the due time. Documentation is not required for incidental absences, but instructors reserve the right to require a Statutory Declaration if you are often absent. Doctors’ notes are not required. You must complete a Statutory Declaration if you are absent from a midterm or final exam. Statutory Declarations can be completed at the Faculty of Science Office in the Biological Sciences Bldg.


GRADING: Assignments (25%), Midterm (25%) and Final Examination (50%).

An overall course mark of 60% or more guarantees a passing grade of at least D. An overall course mark of 95% or more guarantees a grade of at least A.


ACADEMIC INTEGRITY: "The University of Alberta is committed to the highest standards of academic integrity and honesty. Students are expected to be familiar with these standards regarding academic honesty and to uphold the policies of the University in this respect. Students are particularly urged to familiarize themselves with the provisions of the Code of Student Behaviour (online at and avoid any behaviour which could potentially result in suspicions of cheating, plagiarism, misrepresentation of facts and/or participation in an offence. Academic dishonesty is a serious offence and can result in suspension or expulsion from the University." 

All forms of dishonesty are unacceptable at the University.  Any offence will be reported to the Associate Dean of Science who will determine the disciplinary action to be taken. Cheating, plagiarism and misrepresentation of facts are serious offences.  Anyone who engages in these practices will receive at minimum a grade of zero for the exam or paper in question and no opportunity will be given to replace the grade or redistribute the weights.  As well, in the Faculty of Science the sanction for cheating on any examination will include a disciplinary failing grade (NO EXCEPTIONS) and senior students should expect a period of suspension or expulsion from the University of Alberta.
