# UM Math 215 On-Line Homework F23

## Hints and Tips

1. Start early, when each set opens.
2. Do the example set (homework0). It's easy & will help you with the homework system.
3. Don't submit partial answers. You have six submissions per problem.
4. Work the problems out by hand before entering them in the system. You can get a hardcopy of a problem set from the problem listing page of a problem set.
5. Always preview your answers before submitting them.
6. Use calculator syntax:
1. Carefully parenthesize. Type `cos(2pi)`, `e^(-ln(3))`, or `1/(1+x)`, not `cos 2pi`, `e^-ln3` or `1/1+x`. Note that `sin2x` is read as `sin(2)*x`, which is probably not what you want. Enter `sin(2x)` instead.
2. The square root is `sqrt(x)` or `x^(1/2)`.
7. Watch your case: `X` is different from `x`, `Sin` is different from `sin`, and `Pi` is different from `pi`. You want `pi`.

## Important Info

1. Your username for the web homework is your uniqname. Your password is your Kerberos password that you use to work with other on-line University applications.
2. Due dates for the web homework are available in the web homework system.
3. Help on the homework is available from your GSI, and your instructor, and Math Lab (B860 East Hall). You can also get help by clicking the "email instructor" button in the homework.
4. Late questions (e.g., e-mailed questions asked the day an assignment is due) are not guaranteed to be answered.
5. You can practice the homework problems after the due date.
