Homework

bulletHomework will be assigned during each lecture.  Assignments are due at the end of the next lecture.  This is intended to support continuous learning.
bulletHomework assignments are available in class and posted on the website
bulletScoring:  Your grade will be proportional to the number of problems that you work.  If you only work one problem and there are two assigned, the most that you can get is 50%.  Given that,
- Full credit:  the work that is submitted satisfies all four of the following criteria:  (a) organized presentation, (b) correct method(s) used and written out to document your work, (c) correct answer, and (d) turned in on time.
- Partial credit:  partial credit will be awarded for work that partially satisfies the above criteria.
 
bulletFormat Considerations: The following aspects will also count toward your homework grade:
--- Format for grader and professor - Multiple pages stapled, name/assignment # on top of inside page, name/class/assignment # on folded outside, engineering paper preferred.
--- Format for your understanding - always cast your work in the context of Given... Find... and Box your answer.  For some of your problems, "Given" might be "given our course notes and text", or "Given the information in appx Table A.3..."
--- Units are critical - whenever any magnitudes are reported, report UNITS.
bulletLate homework is accepted until 4:30pm the day it was due.  Homework turned in later than that will be accepted only when a student has received instructor approval, will receive only up to 50%, and only until solutions are posted.
bulletSolutions to homework problems will be presented on this web site.
