Astrophysics 217 Homework Assignments

You are expected to turn in the following homework assignments during the semester, by the dates listed (exercise numbers refer to the ends of chapters in An Introduction to Modern Astrophysics, 2nd edition, unless otherwise noted). . These will not be graded but will be be checked for completion. This counts 25% of your lecture grade. You will be penalized 25% per day for each day that an assignment is late. This is meant to keep you from getting behind; if there are reasons why you need to be late with an assignment, check with me and we can probably reach an arrangement if your reason is legitimate. The homework assignments should be turned in to me at the end of lecture on the day they are due.

Where solutions are provided, you are expected to do the homework before consulting the solutions. You may work together on the homework assignments as long as each person is doing all the problems (That is, it is not permissable for a team to divide up the work and then copy from each other). You are encouraged to learn to use tools like Maple, Mathematica, MatLab, or programming languages in solving problems and graphing solutions.

Note that all assignments and due dates are subject to modification, so you should check this table regularly to be certain about current assignments and their due date. (Problems denoted by * are optional extra credit.)
