• Correction to today's first problem: Please replace the constraint for x^2 + y^2 to be at most 2 (not 1). Then (-1,-1) solves the problem.
• Topics for tomorrow's lecture: concavity/convexity of composite functions, and then linear-quadratic constrained optimization with an application to finance.
• I will put up a voluntary term paper problem set, or maybe even two. Question: Does anyone want an extra lecture Wednesday after Easter for one such problem set? I will discuss with you tomorrow. If so, I will cover the spring 2011 exam in that lecture; you might do that as a voluntary term paper. (An alternative would be the autumn 2007 set).
• Midterm evaluation forms. I have been informed that this course is subject to midterm evaluation. Will spend ten minutes of tomorrow's lecture on that as well.
