Basic Course Information
Prerequisites:Math 243 with a grade point of 2.000 or better, or departmental consent.
Course Description:
A study of first order equations including separation of variables and exact equations, second order equations including the general theory of initial value problems, constant coefficients, undetermined coefficients, variation of parameters and special methods of solution using power series and the Laplace transform methods. A standard course in differential equation for students in the sciences and engineering.
Required Resources:
The main reference for this course is:
Book: Elementary Differential Equations, 10th edition, W. E. Boyce & R. C. DiPrima, John Wiley & Sons, Inc., 2012.
Class Protocol:
Attendance is required, but will not be factored into students' grades. If students are not present, they will not be able to complete the activities that correspond to that day's discussion and work in class. Students are asked to be on time, and to notify the instructor if they will be absent. They are asked to observe common norms of civility in class and in interactions with the instructor and with classmates outside of class.
Detailed Course Information
Course Content:Graded coursework will cover most of Chapters 1-6 and small sampling of Chapter 8 of the required text listed above.
Assignments and Coursework:
The coursework for this class will be divided into three categories.
Quizzes (15%):
Timed quizzes will be given throughout the semester. Questions on the quizzes will be similar to the recommended exercises (see below) and examples presented during lectures. These quizzes will be open-book/open-notes. Calculators and electronic devices will usually not be allowed.
Unit Exams (45%):
There will be three (3) 50-minute exams throughout the semester. There will be no make-ups, except in extreme, documented, circumstances.
Amendment: (08 May 2019) As discussed in class, since a fourth test was added, the lowest unit exam grade will now be dropped. The three highest unit exam grades will be averaged and counted as 45% of your final grade.
Numerical Project (15%):
There will be a project using Excel or a similar program/language to approximate solutions to real-world examples of differential equations. The project will consist of a take-home portion as well as an in-class written portion. This project is designed to cement ideas from the entire semester through approximation methods that will be useful in students' future work.
Comprehensive Final Exam (25%):
The final exam will cover material from the entire semester. The final exam must be taken during the scheduled final exam period determined by the university.
Grading:
Students' final letter grades will be calculated according to the following table. Final percentage grades will not be rounded up, and there will be no extra credit.
| Letter Grade | Numerical Percentage | Grade Points | Comments |
| A | 90 - 100 | 4.0 | The A range denotes excellent performance |
| A- | 88 - 89.99 | 3.7 | |
| B+ | 86 - 87.99 | 3.3 | |
| B | 80 - 85.99 | 3.0 | The B range denotes good performance |
| B- | 78 - 79.99 | 2.7 | |
| C+ | 76 - 77.99 | 2.3 | |
| C | 70 - 75.99 | 2.0 | The C range denotes satisfactory performance |
| C- | 68 - 69.99 | 1.7 | |
| D | 60 - 67.99 | 1.0 | The D range denotes unsatisfactory performance |
| F | < 60 | 0.0 | The F range denotes failing performance |
Measurable Student Learning Outcomes
Upon successful completion of this course, students will be able to:|
a.) Classify differential equations and initial value
problems. b.) Model simple physical systems to obtain a differential equation (DE) or initial value problem (IVP). c.) Visualize solutions to first order DE's using direction fields and approximating solutions with Euler's method. d.) Determine and classify critical points of a first order autonomous equation; use them to describe the behavior and stability of solutions. e.) Understand the basic notions of linearity, superposition, existence and uniqueness of solutions when solving a linear DE. f.) Demonstrate proficiency solving DE's using the characteristic equation, undetermined coefficients, variation of parameters, elimination, complex arithmetic, power series at analytic and near singular points, recurrence relations, indicial equations, Laplace transform, convolution integrals, transfer functions, integrating factors and integration by parts. g.) Determine the interval or region of existence, uniqueness and stability of a solution to a DE or IVP. |
University Policies and Procedures
Academic Honesty:Students are responsible for knowing and following the Student Code of Conduct and the Student Academic Honesty policy.
Definition of a Credit Hour:
Success in this three-credit-hour course is based on the expectation that students will spend, for each unit of credit, a minimum of forty-five (45) hours over the length of the course (normally three hours per unit per week, with one of the hours used for lecture) for instruction and preparation/studying or course related activities for a total of 135 hours. Read this to learn about the policy and examples of different types of courses and credit hour offerings.
Important Academic Dates:
Wichita State University's full academic calender can be found here.
Disabilities:
If you have a physical, psychiatric/emotional, or learning disability that may impact on your ability to carry out assigned course work, I encourage you to contact the Office of Disability Services (DS). The office is located in Grace Wilkie Annex, Room 150, 316-978-3309 (voice/tty) and 316-854-3032 (videophone). DS will review your concerns and determine, with you, what academic accommodations are necessary and appropriate for you. All information and documentation of your disability is confidential and will not be released by DS without your written permission.
Title IX:
Title IX of the Educational Amendments of 1972 prohibits discrimination based on sex in any educational institution that receives federal funding. Wichita State University does not tolerate sex discrimination of any kind including: sexual misconduct; sexual harassment; relationship/sexual violence and stalking. These incidents may interfere with or limit an individuals ability to benefit from or participate in the Universitys educational programs or activities. Students are asked to immediately report incidents to the University Police Department, (316) 978-3450 or the Title IX Coordinator (316) 978-5177. Students may also report incidents to an instructor, faculty or staff member, who are required by law to notify the Title IX Coordinator. If a student wishes to keep the information confidential, the student may speak with staff members of the Counseling and Testing Center (316) 978-3440 or Student Health Services (316)978-3620.
