Course Prerequisites: PY 205 (Corequisite MA 242)
Before an engineering student or computer science student is eligible to enroll in a 200 or higher level engineering course, the student must have earned a grade of "C" or higher in ENG 111, CH 101, CH 121, MA 141, MA 241, and PY 205, have passed either CH 107, CSC 110, CSC 112, or CSC 114, and have satisfied any other pre-requisites of the course.
Regular attendance is expected of all students. Students who do not attend classes (except when excused due to documentable illness, catastrophic family problems or official representation from NCSU) forfeit their right to take up instructor's time (both in and out of class) to cover the material which was missed.
Students will be required to sign an honor pledge for all tests and assignments. Anyone found cheating would be expelled from class with an automatic "F" grade. Students may work in groups on homework assignments to discuss solution techniques and exchange ideas. However, each student must turn in homework set that represents his or her individual work (i.e. no group Xerox copies or group homework sets).
Homework:
There will be approximately 12 homework sets. Each set will be worth ten points. 50% of each homework set grade is for completeness, and the other 50% is for correctness. The correctness of solutions will be graded based on two or three problems in the homework set. At the end, the lowest two set scores will be dropped. Homework must be turned in at the beginning of the class on the day it is due. Late homework will not be accepted. Mark the outside of the homework set with your name, the date it is due, and the homework set number. See "Homework guidelines" for more information on homework requirements.
Make a photocopy of your homework and put it in your file before turning it in. There is no guarantee that graded homework will be returned before an exam. Homework solutions will be posted and you can compare your solutions with the correct solution and study for exams. The instructor is not responsible for lost homework if you don't pick it up from my office promptly.
Tests:
There will be three tests during the semester and a comprehensive final exam. The tests will be given at normal class times. Tests missed without valid causes (e.g. a doctor's certificate) will be graded zero and no make up will be given. NO EXCEPTIONS. Bring a calculator to each test and the final exam.
Course Grade: Homework Sets: 10%; 3 Tests: 60%; Final: 30%.
Homework Guidelines:
1. Use one side of 8.5" x 11" paper only for all assignments. Paper tom out of spiral notebooks will not be graded.
2. Put your name, page number, at the top of each page and the date the assignment is due. Use a numbering system like 1 of 5, 2 of 5, or 1/5, 2/5.
3. Each problem should be numbered clearly. Your writing should be neat and legible. Your sketches should be neat and clear. Use straight edge or template if necessary.
4. Your solution should proceed step by step. Don't skip critical steps. Partial credits cannot be given if you don't show your steps in arriving at your answer.
5. Box-in your final answer and make them stand out.
6. Use proper units and the final answer should be rounded to three significant digits.
7. Staple your work in the upper left-hand corner. Fold lengthwise, and write your name, date, and the homework number on the outside.
8. Turn in your homework at the beginning of class time. No homework will be accepted in my office. No Late homework will be accepted.
