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.
