Note(s) updated, and next week

• Most recent lecture note updated: the 2's on page 8 are fixed, and the last application is written out on two new pages 12-13.
  Also, since nobody needed both "landscape" and "portrait", I rationalized away the latter.
• Week 9: not unlikely, there will be seminar on Thursday 14-16, and lecture Friday 12-14. (Objections ASAP, please.)

If so, the rest of the semester could look like the following: 

• Wk 9: optimization 
• Wk 10: trig. functions, 2nd order diff.eq's
• Wk 11: differential eq. systems
• Wk 12: either double/multiple integrals, or difference equations & (discrete-time) dynamic programming
• Wk 13: Easter
• Wk 14: calculus of variations & (continuous-time) optimal control
• Wk 15: optimal control
• Wk 16: multiple integration
• Wk 17: there will then be only one lecture left (not two), and that can be postponed to a review lecture close to the exam.
