Math 343 – Fall 2014
1/??
Problem Sets Between Tests 1 and 2
Only turn in problems that are not bracketed. Bracketed problems are additional problems you can look
at. Round brackets indicate problems that may help you with problems that are assigned; square brackets are
additional problems on material that you should know, but you are not required to write up solutions; curly
brackets are truly optional and may contain extra nuggets that you will not be required to know but may be
interested in.
Additional assignments will be filled in over time.
