Pre-requisite:Math 20524
Text: Differential Equations (4th edition) Blanchard, Devaney and Hall (Brooks/Cole): ISBN-13 978-1-133-10903-7.
Calculator:A TI-83 calculator is recommended. Calculators that perform symbolic manipulation (such as the TI-89 or TI-92) will NOT be allowed on exams.
Goals: The student should obtain a basic understanding of differential equations, including the aspects of mathematical modeling (the meaning of the equations) and ability to solve certain kinds of equations. The topics will include modeling with differential equations, first order equations, second (and higher) order linear equations, and the Laplace transform.
Grades: Grades will be based on Homework and Quizzes (10% each), three Exams (15% per exam) and the Final Exam (35%). I will regularly assign homework. Discussion with classmates is alright, but copying is not. There will be quizzes during many lectures with problems based on the homework. Usually the quizzes are announced in advance, but this is not guaranteed.

When all the coursework is complete, grades will be assigned on the following basis. Let P be the percentage of points scored. Then

P Grade
P at least 90 A
P at least 88, but less than 90 B/B+/A-/A, depending on strength of final
P at least 80, but less than 88 B
P at least 78, but less than 80 C/C+/B-/B, depending on strength of final
P at least 70, but less than 78 C
P at least 68, but less than 70 D/D+/C-/D, depending on strength of final
P less than 68 D or F
Attendance and make-up policy: University policy states that regular and punctual class attendance is essential and that no assigned work is excused due to absence, no matter what the cause. If you miss a quiz due to absence it will count as a zero, except in cases of excused absence (these require a note from Campus Life or documented participation in university activities). Makeup exams are possible for students with an excused absence, in which case the student must inform me before the exam.
Exams: There will be three exams during the semester and a final. Please bring your calculators. The tentative dates for these exams are given above, however they are subject to change. I will announce any changes to exam dates in class at least a week in advance.
Course Website: I will maintain this website for our course; it will contain homework assignments, solutions, and other useful information. The address is www.math.tcu.edu/math/faculty/Nollet/courses/diffeqs.html.
Disabilities statement: Texas Christian University complies with the Americans with Disabilities Act and Section 504 of the Rehabilitation Act of 1973 regarding students with disabilities. Eligible students seeking accommodations should contact the Coordinator of Student Disabilities Services in the Center for Academic Services located in Sadler Hall, 1010. Accommodations are not retroactive, therefore, students should contact the Coordinator as soon as possible in the term for which they are seeking accommodations. Further information can be obtained from the Center for Academic Services, TCU Box 297710, Fort Worth, TX 76129, or at (817) 257-6567.

Adequate time must be allowed to arrange accommodations and accommodations are not retroactive; therefore, students should contact the Coordinator as soon as possible in the academic term for which they are seeking accommodations. Each eligible student is responsible for presenting relevant, verifiable, professional documentation and/or assessment reports to the Coordinator. Guidelines for documentation may be found at http://www.acs.tcu.edu/disability_documentation.asp.

Academic Misconduct (see section 3.4 from Student Handbook) Any act that violates the academic integrity of the institution is considered academic misconduct. The procedures used to resolve suspected acts of academic misconduct are available in the offices of Academic Deans and the Office of Campus Life. Specific examples and more details are in the Student Handbook.
