Lecture sketches and homework

To help you study for this class, I am posting lecture sketches. These are not a substitute for your personal lecture notes or coming to class (for instance, lots of details and motivation are not included in the sketches). I hope that they are useful to you for revisiting the material and for preparing for exams.

After most classes, homework is assigned and posted below.

  • You should aim to complete the problems right after class, and before the next class meets.
    A 15% penalty applies if homework is submitted after the posted due date.
  • Homework is submitted online, and you have an unlimited number of attempts. Only the best score is used for your grade.
    Most problems have a random component (which allows you to continue practicing throughout the semester without putting your scores at risk).
  • Collect a bonus point for each mathematical typo you find in the lecture notes (that is not yet fixed online), or by reporting mistakes in the homework system. Each bonus point is worth 1% towards a midterm exam.
    The homework system is written by myself in the hope that you find it beneficial. Please help make it as useful as possible by letting me know about any issues!
