### Webwork Notes

### Spring 2019

Logging in: a link to the login page is here.

If you *cannot log in*, first check that you have the correct
initial password. Your initial password is the part of your
Binghamton email address before the @. Note that this is
*not the same* as the password for your Binghamton email account.

If you still cannot log in, the most common explanation is that you
added the class after the date the WebWork accounts were created.
In this case you should email your instructor and ask
to have a WebWork account created for you. Be sure to do this from
your Binghamton account.

If both of these fixes fail, please see your instructor.

About unlimited attempts for each homework problem: there is no
penalty for incorrect answers. In particular, getting the answer
wrong 17 times and then getting it right is just as good as getting it
right the first time.

If you need to enter, say, the square root of 3, you can (in most
WebWork contexts) type sqrt(3). Other mathematical functions like
sine and cosine have the obvious abbreviations (sin, cos). The numbers
pi and e are typed into WebWork exactly as they appear in this
sentence. If this becomes a big issue I can assign everyone an
working-with-WebWork problem set in which we practice these
techniques. I hope to avoid this.

There is a small numerical tolerance around correct answers, so you
could also write 3.14159 for pi and the answer would (usually) be
correct.
