Course Procedures

Course Meetings

The class is structured with two large lectures per week where new material will be introduced and old material summarized, one computer studio where you can experiment with different mathematical situations with a partner, and one recitation where you can get help on the homework and other topics in the course.


Written homework will be assigned weekly and is due in the homework box by 5:00pm on the due date. Homework assignments will be announced weekly in class and posted on the class web page. Late homework may not be accepted. There will also be regular online homework assignments posted on the class web page. These assignments will be computer graded with immediate feedback. The problems are randomly generated for each student, and you may try an assignment as many times as you want before midnight of the due date. You will receive your highest score over all your attempts on each assignment.


The course has a weekly computer lab. The assignments will be posted on the class web page and the labs can be accessed from the class web page as well. You will need to attend the lab session to get specific instructions and help on carrying out the labs. You can continue to work on the labs from a computer with a web browser to finish your work, or to review material while writing up your lab report or while preparing for an exam. Written lab reports will be turned into the lab box by 5:00pm on the due date. Please be careful to turn homework into the homework box and labs into the lab box; different people pick up the different types of assignments.

Extra Credit

There will also be a number of extra credit assignments during the term. These assignments will give you a chance to show how well you can do on more involved problems given a week's time. Assignments will be posted on the class web site and announced in class.


The midterm exams for this course will be from 7:15-8:45pm on the following Tuesdays: Feb. 9, Mar. 8, and Apr. 12. Exam rooms will be determined by recitation section and will be announced in class and on the course webpage prior to the exam. Exams may include material from lectures, homework, and labs. The final exam will be comprehensive. The date, time and location of the final exam will be announced in class and posted on the course webpage well before the exam date. All exams will be closed book, but you will be permitted one 8.5" x 11" sheet of handwritten notes. You will also be permitted a calculator (without a QWERTY keyboard). Please let me know as soon as possible (preferably in advance) if you must miss an examination. After each exam is graded, a scale will be posted listing the minimum A, B, C, and D scores on that exam.


Grades will be computed mechanically. We will scale written homework, online homework and lab scores to 80 points each. Exams will be worth 80 points and the final will be worth 120 points. Extra credit will be worth between 40 and 60 points (depending on the number of assignments). We will then total your scores. We will also total the minimum A on the homeworks, labs, exams, and final. Observe that the minimum A score doesn't include the extra credit assignments - those are extra credit that add to your score without changing the cutoffs. If your score is greater or equal to the minimum A score, you've earned an A. If your score is one point below the minimum A score, you've earned a B. Students who have 480 points or more before the final (which is possible if you earn sufficient extra credit) will be excused from the final with an A for the course. If you are excused from the final, you will receive written notification, signed by your recitation teacher. If you don't have a signed note, you aren't excused from the final.

Where to Get Help

Your recitation instructor will announce office hours during which you may seek help. In addition, help sessions are held Monday through Friday during the day in Cardwell Hall. Help sessions begin the second week of class. There will be a help session schedule with specific times posted across from the Math office in Cardwell and also on the Math website. Several instructors will be present to assist you. Tutors for most math courses can be located through the Mathematics Department or through numerous service organizations on campus.

Statement Regarding Academic Honesty

Kansas State University has an Honor System based on personal integrity, which is presumed to be sufficient assurance that, in academic matters, one's work is performed honestly and without unauthorized assistance. Undergraduate and graduate students, by registration, acknowledge the jurisdiction of the Honor System. The policies and procedures of the Honor System apply to all full and part-time students enrolled in undergraduate and graduate courses on-campus, off-campus, and via distance learning. The honor system website can be reached via the following URL: A component vital to the Honor System is the inclusion of the Honor Pledge which applies to all assignments, examinations, or other course work undertaken by students. The Honor Pledge is implied, whether or not it is stated: "On my honor, as a student, I have neither given nor received unauthorized aid on this academic work." A grade of XF can result from a breach of academic honesty. The F indicates failure in the course; the X indicates the reason is an Honor Pledge violation.

In this class, you are authorized to work together on homework, labs, and extra credit, unless otherwise instructed on that particular assignment. It is important to keep in mind that you may not collaborate on the exams. Since it is impossible to do well in this course without passing the exams, it is in your best interest to ensure that your collaborations do not hamper your understanding of the material.

Statement Regarding Students with Disabilities

Students with disabilities who need classroom accommodations, access to technology, or information about emergency building/campus evacuation processes should contact the Student Access Center and/or their instructor. Services are available to students with a wide range of disabilities including, but not limited to, physical disabilities, medical conditions, learning disabilities, attention deficit disorder, depression, and anxiety. If you are a student enrolled in campus/online courses through the Manhattan or Olathe campuses, contact the Student Access Center at, 785-532-6441; for Salina campus, contact the Academic and Career Advising Center at, 785-826-2649.
