Catalog Description: Theory of functions of a complex variable with application to physical and engineering problems. Although not required, skill in vector analysis will be helpful in taking this course. Prerequisite: C (not C) in 264 and one MATH course 300level or above.
Please note the following guidelines for the course:
GRADING: Your total course grade is based on your ranking and percentile in the class computed using the inclass exams, homework, and the final exam scaled as follows:
Not all homework problems will be graded. You will get credit if you turn in the statements of all the homework problems written in the correct order. The Final Exam score will replace all midterm scores that are lower than the Final Exam score. All grades will be posted on UNMLearn. Although a small curve might be used, 90% , 80% or 70% of the possible maximum points guarantees at least an A, B or C, respectively.
To get full credit on exams and quizzes you need to show your work, neatly, in clear and correct mathematical notation, annotated by English sentences where appropriate. You will be graded based on the work shown, not on the answer. All grades will be posted on UNMLearn. If you withdraw after the 3rd week of class, you will receive a W. If you do not withdraw, you will receive a letter grade of A,B,C,D or F (and not a W).
CALCULATORS: We will not use any (graphing or nongraphing) calculators on the exams or quizzes.
EXAMS: The exam dates are given in the syllabus. No makeup exams will be given unless you contact your instructor ahead of time with a documented “university authorized absence” (illness, family emergency, active participation in scholarly or athletic events).
ATTENDANCE: Attendance at UNM and homework is mandatory. If you have missed more than 4 attendance+homework+quizzes in the ﬁrst 3 weeks you will be dropped from the course. Similarly, students with absences and lack of work during the rest of the semester may be dropped. Tardiness or early departure may be regarded as absence. Please note that it is the students responsibility to drop the course if he/she stops attending. A failing grade of F may be assigned if the student stops attending and does not drop. You can find the precise statemenet of the University policy here.
Be courteous and respectful and refrain from any activity that could be disruptive to the class. Cheating will not be tolerated.
ACCESSIBILITY STATEMENT: In accordance with University Policy 2310 and the Americans with Disabilities Act (ADA), academic accommodations may be made for any student who notifies the instructor of the need for an accommodation. It is imperative that you take the initiative to bring such needs to the instructor’s attention, as he/she are not legally permitted to inquire. Students who may require assistance in emergency evacuations should contact the instructor as to the most appropriate procedures to follow. Contact Accessibility Resource Center at 2773506 for additional information
FINAL EXAM: Thursday, December 13, 10:00 a.m.‐12:00 p.m. Students having conflicts with this examination schedule must notify the appropriate instructor before Friday, November 3, 2018. Any student having more than three examinations scheduled in any one day may notify the instructor of the last examination listed. If notified before Friday, November 2, 2018, the instructor shall make arrangements to give a special examination. Conflicts arising as a result of scheduling out of normal hourspattern or day sequences must be resolved by the instructor of the offpattern courses. Changes in this examination schedule are not permitted except by formal approval of the instructor’s College Dean.
HOMEWORK: Homework related material including solutions of some problems will be posted on UNMLearn. The general rule is that homework assigned in one week is due at the beginning of the Tuesday or the first class of the following week. No late homework will be accepted.
