Homework should be turned in at the BEGINNING OF CLASS.
All problem numbers refer to *A First Course in Math and Music*, the primary text for the class (available on Moodle).
You are encouraged to work
on these problems with other classmates, and it is ok to use internet sources for help if it's absolutely
necessary; however, the solutions you turn in should be YOUR OWN WORK and written in YOUR OWN WORDS.
Be sure to cite any references, websites, Internet sources, etc. that you may have used for assistance with the assignment.

** Important: ** Please list the names of any students you worked with on the top of your assignment.

**Section 5.3** (pp. 200-201)

Problems: 1, 2, 5, 7, 9, 10

**Hints:** For #7, you are to construct the group multiplication table for the symmetries of an equilateral triangle.
This is a 6 by 6 table, similar to the one we constructed for the symmetries of the square. First find the two triangles corresponding to the rotations **R _{120}** and
