Below are the notes that I used while teaching Math 2177 recitations at the Ohio State University in the Fall of 2020. Students from future sections of this class may use these as a list of practice problems with solutions to study with. TAs for future sections of this class may decide to present these problems in their recitation sections, possibly even presenting their own solutions, then making these typed solutions available to their students for review later on. For the documents that are typed, I have also separately included the source files incase any other instructor wants to use a modified version of them in their own courses. My latex source files use this class file.
