Recitation

We will have a special recitation in Duke 345 every Tuesday evening from 6:30 - 8:30

Homework

-is due at the beginning of class on the second class from the assignment date.

-may not be accepted late except for instances of sickness or death in the family (in the case of sickness or personal emergency, notify me via email and place your paper in my mailbox as soon as possible).

-must have your full name printed legibly on the top right corner.

-must be done on straight-cut paper (points may be deducted for uneven or frilly edges).

-must be stapled (for multiple pages) (or points may be deducted).

-must NOT be copied from another person or any other source (submitting copied work is a violation of the code of academic integrity, policy 105, which is summarized below).

-must show coherent solution methods (writing the answer down will not earn credit).

-must have proper units on all answers, and all answers should be boxed.

-must have three or four significant figures (and engineering notation is recommended).

-must be neat and legible (if it cannot be read, it cannot be graded).

-will have grades based on selected problems (not all problems will be graded).

Exams

In the event of sickness/health problems or death in the family prior to or on the day of an exam, the student must contact the instructor (by email, in-person, and phone) as soon as possible to make special arrangements regarding the exam. No other excuses may be accepted for missing an exam.

Acceptable Calculators

Attached is a list of acceptable calculators in an exam:

These are the same calculators allowed into the PE exam

  • Casio: All fx-115 models. Any Casio calculator must contain fx-115 in its model name.
  • Hewlett-Packard: The HP33s and HP 35s models, but no others
  • Texas Instruments: All TI-30X and TI-36X models. Any Texas Instruments calculator must contain either TI-30X or TI-36X in its model name.

Important Notes

Students are responsible for regularly checking their university email accounts for notes sent as attachments and for updates regarding the class.

Cellular phone use in class is prohibited.

Professional behavior is expected of all students at all times.

Academic Integrity

Students have the responsibility to know and observe the requirements of the UNC Charlotte Code of Student Academic Integrity, 1999-2000 Catalogue, p. 375, or university website: This code forbids cheating, fabrication and falsification of information, multiple submissions of academic work, plagiarism, abuse of academic materials, and complicity in academic dishonesty. Any special requirements regarding academic integrity in this course will be stated by the instructor, and are binding on the students. Academic evaluations in this course include a judgment that the student’s work is free from academic dishonesty of any type; and grades in this course therefore will be adversely affected by academic dishonesty. Students who violate the code can be expelled from UNC Charlotte. The normal penalty for a first offense is zero credit on the work involving dishonesty and further substantial reduction of the course grade. In almost all cases the course grade is reduced to F. Copies of the complete code can be obtained from the Dean of Students Office. Standards of academic integrity will be enforced in this course. Students are expected to report cases of academic dishonesty to the course instructor.

Course Attendance Policy

Students are expected to punctually attend all scheduled sessions in the course for which they are registered, and are responsible for completing the work from all class meetings. Absences from class may be excused by the instructor for personal illness, religious holidays, or participation as an authorized University representative in an out-of-town event. Wherever possible, students are expected to seek permission of the instructor prior to absences.
