# ASTR 100 (Veilleux) HOMEWORK ASSIGNMENTS

Be sure to try the "Test Yourself" Questions at the end of each chapter (answers are on page AQ-1 after the Glossary) - this is a great way to see if you are absorbing the material. It is also an excellent way to practice for the exams, which will include multiple choice questions similar to these ones. I recommend doing this throughout the semester for each of the chapters that we cover.

Do the same for the "Working with Equations" program. If you have trouble doing either of these problems, be sure to talk to your TA about it. These are the ONLY type of math problems that I will ask you to do on a test.
