## 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!

## Sage

For more involved calculations, we will explore the open-source free computer algebra system Sage.

If you just want to run a handful quick computations (without saving your work), you can use the text box below.

An easy way to use Sage more seriously is by creating an account at http://cocalc.com. This free cloud service does not require you to install anything, and you can access your files and computations from any computer as long as you have internet. To do computations, once you are logged in and inside a project, you will need to create a "Sage notebook" as a new file.

## Exams and practice material

There will be two in-class midterm exams and a comprehensive final exam. Notes, books, calculators or computers are not allowed during any of the exams. The exam schedule is posted in the syllabus and at the top of this page.

The following material will help you prepare for the exams.

- Midterm Exam 1:
- midterm01-practice-lecture.pdf (these are problems we discussed in class)
- Online practice problems (these are compiled from homework)
- midterm01-practice.pdf, midterm01-practice-solution.pdf (these problems are more exam-like)
