Homework Requirements and Comments

• * Note: HW should be submitted at the beginning of class (front table in classroom) on due date. If lecture has begun, do not disturb lecture. Wait until after lecture is over to submit ! HW is considered late after Prof. has left the classroom.
  
  
• Homework must follow specific requirements. See Homework Assignment Requirements. See also note on Significant Digits below.
  
  
• Note on Significant Digits:
  • When performing calculations or manipulations of several parameters, the final result is only as accurate as the least accurate parameter in the problem.
  • Most engineering data (measurement instruments) are good to three to four significant digits. Consider specific data given in problem, tables, etc.
  • When writing out intermediate results in a calculation, it is okay to record more digits than the number which is significant, as this can avoid round-off errors in subsequent calculations. However, when displaying the final answer, the number of significant digits should be taken into consideration.
