• Announcements: Please remember that, as per our day-by-day schedule, our classes this week are being held remotely asynchronously. In other words, you will work through the videos below, and pause to try to solve the exercises I propose before I discuss their solution. Please make sure you complete this material before the end of the week, since it will be needed in your next homework assignment HW3. The current homework assignment (HW2) is due on Wednesday by 11.59pm via Blackboard, and covers only the lectures before today.
