Study Plan: Regular attendance and participation in class activities are the prerequisites for success. Except in extreme circumstances, no accommodation can be given for failure to meet this responsibility.

Ungraded homework assignments will be given regularly. It is essential to solve each homework problem in order to understand the material and develop the necessary skills. If you have a question about an assigned problem, you are encouraged to raise it at the start of the next class. Do not consult a worked solution before seriously attempting to solve a problem yourself.

Communication devices must remain switched off during the class periods and exams.

Syllabus: Selected topics from Chapters 1-7.
