## The graph of the curve with curvature k(s) = 2(2+cos2s)This is the graph of a curve described in terms of a parameter s (arc-length). The formula is not for the function, but for its curvature. You will be able to understand how this is generated at the end of the class/sequence. |

Besides the regular lectures, students are required to attend the smaller discussion sections (twice a week) where TAs will help with the practical aspects of the subject. They are also required to attend group work sessions, scheduled independently by each group. Attendance is absolutely necessary and, although it does not carry any points in the total count (see syllabus) it might be a deciding factor for borderline grades. All students should be engaged in the course, this includes going to the lectures and discussion sessions, readying the notes, doing assignments and thinking about what is done in class.
