• Announcements: Today we proceed with new material, on Lecture 18 of the semester (Lecture 17 was the Midterm Exam). There is a very short new homework assignment (HW7) due next Monday (4/6/2020) by beginning of class, 1:00pm, and it is about the topic of the present lecture: the method of Lagrange Multipliers for constrained optimization. I am still in the process of grading the exam and will upload solutions to the website shortly, so stay tuned for that. As always, if you have any questions, please send me an e-mail!
