The HW contains some exercises (fairly simple problems to check you are on board with the concepts; dont submit your solutions), and problems (for which you should submit your solutions, and which will be graded). Some problems have sub-parts that are exercises. For this problem set, its OK to work with others. (Groups of 2, maybe 3 max.) That being said, please think about the problems yourself before talking to others. Please cite all sources you use, and people you work with. The expectation is that you try and solve these problems yourself, rather than looking online explicitly for answers. Submissions due at beginning of class on the due date. Please check the Piazza for details on submitting your LaTeXed solutions.
