In your mathematical careers, it will be increasingly more important for you to
demonstrate good problem solving skills. The emphasis is shifting from being
able to grind out rote calculations like you did in Algebra and Calculus, to
being able to solve original problems.
And part of problem solving is being
able to explain to others how you solved the problem.
For that reason, your
homework will be graded on how much work you show, and how much you
explain your reasoning. The following is a sample problem along with several
different possible student responses. Each response is graded, and the grade for
each is explained.
