ACE Outcome 3: This course satisfies ACE Outcome 3: “Use mathematical, computational,
statistical, or formal reasoning (including reasoning based on principles of logic) to solve problems,
draw inferences, and determine reasonableness.” Your instructor will provide examples, you will
discuss them in class, and you will practice with numerous homework problems. The exams will
test how well you’ve mastered the material. The final exam will be the primary means of assessing
your achievement of ACE Outcome 3.
Required Textbook: Edwards and Penney Differential Equations: Computing and Modeling,
Fourth Edition. Pearson, 2008. ISBN-13: 978-0-13-600438-7.
Attendance: Due to the sequential nature of this course, attendance is vital for achieving the
outcomes listed above. So, you are expected to attend every class. You are responsible for
any announcements made in class, for the material discussed in class, and for reading the textbook.
Please be advised that more than two unexcused absences and/or recurrent tardiness will
most likely result in your final grade being lowered. Leaving class early is considered the
same as arriving late.
Grades: Your performance in this course will be evaluated using weekly homework, three inclass midterms and a final exam. Approximate dates for these can be found in the course outline.
Your grade will then be computed as follows:
Tests (15% each)
Homework
Final Exam
Class Participation

100%
ADA Notice: Students with disabilities are encouraged to contact the instructor for a confidential
discussion of their individual needs for academic accommodation. It is the policy of the University
of Nebraska-Lincoln to provide flexible and individualized accommodation to students with documented disabilities that may affect their ability to fully participate in course activities or to meet
course requirements. To receive accommodation services, students must be registered with the
Services for Students with Disabilities (SSD) office [http://www.unl.edu/ssd/home], 132 Canfield
Administration, 472-3787 voice or TTY.
Course Evaluation: The Department of Mathematics Course Evaluation Form will be available through your Blackboard account during the last two weeks of class. You’ll get an email when
the form becomes available. Evaluations are anonymous and instructors do not see any of the responses until after final grades have been submitted. Evaluations are important—the department
uses evaluations to improve instruction. Please complete the evaluation and take the time to do so
thoughtfully.
Departmental Grading Appeals Policy: Students who believe their academic evaluation has
been prejudiced or capricious have recourse for appeals to (in order) the instructor, the departmental chair, the departmental appeals committee, and the college appeals committee.
