In the second half of the semester, we’ll be working on creating an annotated study guide for use in preparing for the final. Everyone will be responsible for creating a guide explaining how to do one type of problem.
Assignment (Due Thursday, April 4, 2:30pm). The list below gives an overview of topics/types of problems covered in the class. In this assignment, you should choose THREE of the following topics that you think are interesting or might like to work on. One or more of your choices must be from the second half of the class (items 10-18, things we have not studied yet). Don’t be afraid to choose a topic you don’t know – you will have opportunity to learn, ask questions, and get help along the way! Respond to this post, including your top three choices (give both the number and name of your choice, for example “my first choice is: #5, probability and counting”).
