In some cases these chapters will be covered quite thoroughly and in others only selected topics will be discussed.

LECTURES AND RECITATIONS: The main lectures for this course take place on MWF, and each student is also assigned to one of six recitation sections which meet on Thursdays. The essential course content will all be presented during the MWF lectures. Time in the Thursday recitation classes will be spent on i) review of main points from the lectures, ii) additional examples,  iii) discussion of homework problems, and (iv) quizzes. 


OFFICE HOURS:  For help with course content you may take advantage of group office hours scheduled by any MATH 266 or MATH 267 instructor.  The current schedule is posted here.  Please see me or your recitation instructor for other kinds of questions, including  your own grades, turning in homework, etc. 

Three hour exams   20% of grade each
Quizzes and homework   15% of grade
Final exam   25% of grade

HOMEWORK:  The WebAssign online homework system will be used for most of the homework. Working these problems in a careful and timely manner is the most important way you have to learn the material. Normally a new assignment will appear on WebAssign at the beginning of each MWF lecture, except for exam days and the last week of class, due 7 days later. Some additional, supplementary problems may occasionally be assigned-- these will be announced on Blackboard.

EXAMS: These will take place during the regular class lecture time on September 23, October 23 and November 20.  Exam problems will be very similar to homework problems. I will clarify a week or so ahead of time exactly what topics will be covered on each exam. The final exam time and place will be posted here as soon as it is available.

QUIZZES:  There will be quizzes given during the recitation class on September 10,  October 8, November 5, and December 10. They will take about half the class, and specific topics to be covered will be announced a week or so ahead of time.

CALCULATORS: Calculators are allowed, but not required, on quizzes and exams unless otherwise stated. During quizzes and exams you may not use a calculator which is also a communications device.  Calculators are meant as a convenience for the routine aspects of problem solving, but not as a replacement for the understanding of the concepts and methods which make up this course. As in any other mathematics course you should expect to have to demonstrate your competence by showing your work on anything which gets graded.

SOFTWARE: There will be some limited use of MATLAB in homework assignments, and I will provide some basic information about how to use it at the appropriate time.  You should  find a computer system that you have easy access to on which MATLAB can be run -- see me if you need suggestions about this. 

ELECTRONIC DEVICES: Cell phones and other communications devices should be turned off during class time. In the event that a student needs to keep his/her cell phone on for an emergency, please notify the instructor before class. During class time, laptop computers should only be used for class appropriate purposes.

OTHER RESOURCES: More course information and announcements can also be found via Blackboard Learn where you can also keep track of your grades.

If a student has a disability that qualifies under the Americans with Disabilities Act and Section 504 of the Rehabilitation Act and requires accommodations, he/she should contact the Student Disability Resources (SDR) office for information on appropriate policies and procedures. SDR is located on the main floor of the Student Services Building, Room 1076; their phone is 515-294-6624.
