syl1275 is a description of course and grading components and schedule_v3 is a calendar with homework assignments and exam dates.

session 14 has some supplementary homework problems on perpendicular bisectors available on the department website.

There is no webwork problem set for the trig identities. Hence, I am providing a scan of the textbook exercises.

If for whatever reason you can or do not want to purchase the textbooks used by the course, there are some alternatives that you can try:

1. algebra:https://open.umn.edu/opentextbooks/BookDetail.aspx?bookId=12 and https://open.umn.edu/opentextbooks/BookDetail.aspx?bookId=240
   
2. trig: https://open.umn.edu/opentextbooks/BookDetail.aspx?bookId=57
   
3. algebra and trig: https://open.umn.edu/opentextbooks/BookDetail.aspx?bookId=239

These are all from one online library. If you find other free textbooks, try them out and let me know if they should be shared with the rest of the class.
