**Description of Course**:
Ordinary differential equations and applications; first-order equations; higher order linear equations; systems of linear equations, Laplace transforms; introduction to nonlinear equations and systems, phase plane, stability.
This course covers basic theory and methods of solution for differential equations. The major part of the course deals with linear differential equations and systems of linear differential equations. Laplace transforms are among the tools introduced for the solution of these linear differential equations. There usually are two or three hour-long exams during the semester and a comprehensive final exam. Depending on the instructor, part of the grade also may depend on homework or weekly quizzes. Although the course is part of the engineering mathematics sequence, it is not restricted to engineering students. The course is taught by faculty.

**Prerequisites:** (MATH:1560 or MATH:1860) and (MATH:2700 or MATH:2550)

**Objectives and Goals of the Course**:
See course website for a list of sections we will
cover.
By the end of this course, you should

1.) have a good understanding of the sections covered in class and via
assigned readings.

2.) Be prepared for more advanced courses.

3.) have developed online skills that may be helpful in the job market.

You should read all sections/handouts/web material corresponding to covered material and/or assigned problems. There may be test questions related to this reading even if not covered in class.

*Grading system:*

HW and Quizzes: 15% | 90% <= A- < 91% <= A |

2 out of best 3 exams: 60% | 80% <= B- < 81% <= B < 89% <= B+ < 90% |

Final: 25% | 70% <= C- < 71% <= C < 79% <= C+ < 80% |

60% <= D- < 61% <= D < 69% <= D+ < 70% | |

F < 60% |

*GRADING & EXAMS: *
3 exams and a final will be given.
The lowest score of your 3 exams will be dropped, making the other 2 exams worth 30% each. Your final exam score will **NOT** be dropped. All quizzes and exams are open book and open notes.
Calculators will be allowed. All exams will be cumulative, but some sections may be emphasized over others. These sections will be announced in class.

Exams will be a combination of

- Problems requiring written answers which you will scan in (or take picture) and upload to ICON.
**All work must be shown in order to receive credit.**Important note: If no work is shown, you may receive zero credit even if your answer is correct. - Multiple choice including true false (taken on ICON).

*Quizzes:* We will also have a number of ICON quizzes.

**A Word about the Date and Time of the Final Exam:**

The final examination date and time will be announced by the Registrar generally by the fifth week of classes. I will announce the final examination date and time for this course at the course ICON site once it is known. Do not plan your end of the semester travel plans until the final exam schedule is made public. It is your responsibility to know the date, time, and place of the final exam.

This course may not be curved, but improvement may be taken into consideration.

**Attendance and absences**: Your attendance at each scheduled
class meeting and problem section is expected. You are
responsible for material covered in class and announcements made during
class; these may include changes in the syllabus. Absences from exams will require a compelling reason, and must be arranged with your instructor in advance. University regulations require that students be allowed to make up examinations which have been missed due to illness, mandatory religious obligations, or other unavoidable circumstances or University activities

**Student Collaboration: **You may collaborate with other students
on the homework;
however, each individual student is responsible for turning in your own
homework in your own words. Copying is not collaboration and will
be prosecuted under scholastic dishonesty. **Any significant
collaboration should be acknowledged. You should also cite any sources
that you use including online resources.**

**Note: If you cheat, my lecturing pace may increase as I will think you have a better understanding of the material than you actually do. Whereas if you have difficulty on (part of) a problem, then I know I need to review that material. Also, I will do the paperwork if you are caught cheating.**
