Primary Text:

 

Reference Material:

 

Exams: Includes closed-book, closed-notes section and another section in which equations are provided by instructor.   No other information sources can be used (except your own brain)

 

Assignments:

·         Discussing formulation of problems and approach is fine but each student must work the final solutions alone.

·         All assignments must be completed on the date indicated, however, they will NOT be turned in.  Instead...

·         Several (approx. 4) homework quizzes will be given in class and numerical grades will be assigned.  These homework quizzes will consist of one or two problems identical or very similar to the assigned homework.

 

Computer Projects:

·         For computer problems, each program and report the student uses and/or turns in must be a completely original work by that student.  No pre-existing, or "canned", routines are to be used except those provided by the instructor.

·         Projects are due at the beginning of class on the date indicated.

·         Projects are deducted 10% credit if received by the subsequent class period.  Projects that are more that 1 class period late are not accepted (except documented emergency).

·         A numerical grade will be assigned to each computer project.

 

Honor Code: Students in this course and all other course at Georgia Tech must abide by the Georgia Tech Honor Code.  Please read the text of the Georgia Tech Honor Code which can be found on the internet at http://www.honor.gatech.edu/
