Getting Started With COW
Calculus on the web (COW) is an on-line homework site at Temple University.
You will use COW both as a source of practice (ungraded) homework problems
to complete graded on-line homework assignments. To have your graded homework
recorded in the COW gradebook you must create a permanent COW password.
Read on. (Anybody can practice on COW without a password but practice session
are not graded.)
- Temporary COW password: You will receive an e-mail message from
me when your temporary password is available, sometime during the first two
of the term. Your temporary password will be CurrentTermOnidUsername.
For example, if the current term is S2004 and your Onid e-mail address
is firstname.lastname@example.org, then your temporary COW password will be S2004mathwiz.
temporary password. You
will not be able to access the COW assignments for this course until you
get your temporary
password and change it to a
- Create a permanent COW password: Read the following
- Login to the COW web site
- When there, click on Login, then on Password Exchange.
- On the next screen enter your names as requested, choose Oregon State
University from the school menu, and enter the COW temporary password (see
above) in the field labeled Enter your school ID. (DO
NOT enter your OSU student ID).
- Then click on New. This will allow you to pick your own permanent
password. Pick a password that you will not forget!
Then click on Install. I will not know your permanent password. It
is the password you will use to start a recorded COW session.
Now you are ready to use COW. Here's how:
- To explore COW for the first time, click
here and set a bookmark for future use. Look around the COW homework
site and go to Overview > Student Manual and read through
the short manual. Really, read it!
- Login for a graded or ungraded COW session: Once you have a permanent
COW password, the login procedure for establishing a graded COW session is
to go to the COW web site, click the Login button, and enter the requested
information. To establish an ungraded COW session simply go to the COW web
site and don't use the Login button.
- Which homework problems in COW are assigned? When are they due?
When you login for a recorded session you will see a button labeled Homework.
Click on it to get a list of homework assignments and their due dates. (You
may find it helpful to print out the list of problems in a particular assignment.)
- Most COW homework due dates come well after you should
have finished solving the assigned problems. Your should start working
COW assignments as soon as the topic of the assignment has been introduced
- Homework in COW works just like traditional homework. You can work on an
assignment for a while, logoff, come back to it later any number of times
before the due date. If you miss a problem several times before getting it
correct, you get full credit for solving the problem, providing of course
that you get the correct answer before the due date of the assignment.
- Want to save time and aggrevation? Use the COW Interpreter to find
out what COW thinks you mean. You
input mathematical expressions into COW much like you input data into a
calculator or a computer algebra system. For example, 2^x means 2 raised
to the exponent x. When you first use COW, you may input an expression that
one thing to you and another to COW. To learn how COW will interpret your
input do the following (whenever you like): Input your expression into a
COW dialog box for the problem you are solving. Then click on the Expression
Interpreter link underneath the box. A new dialog box opens with
your input in it. Click on Interpret and COW will show you how it
will interpret your input. With a little practice you and COW will quickly
and you will only occasionally need the Expression Interpreter, but don't
forget it is there.
