If you are registered for Math 190, your final grade will be based on your homework.
Students are encouraged to work together on the homework in partnerships, as it is useful to be able to trade ideas and insights with your peers. But care is required in this electronic age to ensure that copying of other students' solutions doesn't occur. The name (or names, in the case of group work) of students on the homework informs the professor who did the composition, typing, and computing. Communication with other groups should be limited to conversations about ideas, so that when it comes time to compose your homework assignment, you are working from your own personal intellectual understanding of the problem at hand. This is meant to be beneficial for you, so that you will learn and understand the material, and perform well on exams.
