Since we did not complete all material needed to solve hmwk #5 (we did not discuss how to check linear independence of the set of functions via the Wronskian and also material of section 3.5) I suggest you two options for submission of hmwk # 5 with the possibility to earn an extra credit if you submit it earlier:

Option 1: Submit it on Monday, February 25. In this case I will add to your grade after the grading extra 10% of this grade (for example, if after the grading your grade will be 100, I will add extra 10 points to it; if after the grading your grade will be 80, I will add extra 8 points to it).

Option 2: Submit it on Wednesday, February 27, then extra 10% will not be added to your grade
.

Since we did not complete all material needed to solve hmwk #4 (namely we did not discuss spanning sets) I suggest you two options for submission of hmwk #4 with the possibility to earn an extra credit if you submit it earlier:

Option 1. Submit it on Friday, February 15. In this case I will add to your grade after the grading extra 5% of this grade (for example, if after the
grading your grade will be 100, I will add extra 5 points to it; if after the grading your grade will be 80, I will add extra 4 points to it). Note that you
also have 20 pts bonus there so the maximal grade you can get, if you do all bonus questions and submit it on Friday is 126.


Option 2.  Submit it on Monday, February 18, then extra 5% will not be added to your grade and maximum grade you can get in this case is 120.
