# Webwork Homework Answers

After you log into WeBWorK you will go to the main page, which looks similar to the following:

Homework assignments are listed in the middle of the page, and can be in four different states.

- HW3 is an example of a homework set that is
**open**, meaning that you can solve the problems for credit. Next to the link to the homework assignment, it states the date and the time in which the homework assignment is due. - HW4 is an example of a homework set that is
**not open yet**, meaning that it will open sometime in the future. You will not be able to view this homework set. Next to the name of the homework set, it states the date and time in which the homework set is due to open. - HW2 is an example of a homework set that is
**recently closed**, meaning that you may not answer the questions anymore for credit, but answers have not been posted yet, either. If there is a link to the homework set, you can click on it and access the problems and work them out as usual, except you will not get any credit. Your professor has the option of restricting access to closed homework assignments. - HW1 is an example of a homework set that is
**closed**, meaning that you may not answer the questions anymore for credit, but answers have been posted for viewing. Your professor has the option of restricting access to closed homework assignments.

Once you click on a homework assignment that is accessible, you will be taken to the main page of the homework assignment, which looks similar to the following:

In the middle there is a list of problems. Once you click on a problem link to will be taken to that problem:

The problem will be shown in the middle of the page, and there will be blank(s) in which to enter your answers. Although you will enter your mathematical answers in plain text, you can click on **Preview Answers** to see your entry in a nice mathematical form. Once you have an answer you want to submit for grading, click on **Submit Answers**. You will then be told if you got the answer(s) correct or not.

On the left-hand side of the page, you will see a listing of the problems in this homework set, for easy access to other problems. Also, at the top of the page you will see buttons which assist in navigating through the current homework assignment: you can go to the previous problem (unless you are at the first problem), you can go to the main problem page of the homework assignment, or you can go to the next problem (unless you are at the last problem).

*WeBWorK*is a system that allows you to submit solutions online to problems assigned each week.

In

*WeBWorK*, you can try to answer homework problems more than once. After each try, a message tells you immediately whether your answer is right or not. This allows you to try to find out what you did wrong and, I hope, to understand the question better.

*WeBWorK*is supposed to be a learning tool for students and ultimately it functions on an "honor system."You can help each other with ideas or hints on the problems, or to get over some point where you're stuck. But in the end you are to solve the problems yourself and submit your own work.

Actually doing problems for somebody else just intereferes with an opportunity for people to learn and get feedback, and getting a few points boost in the WebWorK score doesn't contribute that much to the overall course grade anyway. In any case, WebWork problems will usually vary slightly from student to student so that just "knowing the answer somebody else got" usually won't help. If there are indications (from the computer system, or otherwise) that you are not doing so, it may constitute an academic integrity violation.

We will using

*WeBWorK*very briefly in class. Then you should go to the WebWorK page (and probably "Bookmark" it on your computer for the semester). From this page, select the link for Math 131 and logon to WebWorK.

First Time Logging On You will need a username and a password. Your username is your 6-digit WU Student ID Number and this is __also__ your initial password. This is a terrible choice for a password -- so after logging in the first time, you should immediately:

- Change your password to something else
- Use the menu to update your email address, if necessary. This will let me or the WebWorK coordinator respond to any message you send us from within WebWorK.
- What if I forget my password? Send an e-mail your instructor who will be able to reset your password. Or, instead, you can send a message to webwork@math.wustl.edu

*WeBWorK*is fairly easy to use, and many of your initial questions during the first couple of weeks can probably be answered on one of the following pages. Otherwise, send me an email: Ron Freiwald

There is a set of "

__Review Problems__" now available for practice. These problems will let you review some of the precalculus review material in Section 1.1 - 1.6 that we are not going to discuss in class, and they will let you see how to enter answers in WebWorK. Generally, the syntax is very much like what you find on a graphing calculator -- for example, x^2 is entered to represent x

^{2}and sqrt(x) is used to represent "the square root of x." Any solutions you submit (or don't submit) for the questions in the review set will not be counted toward your

*WeBWorK*score for the course.

On Monday, September 6 (even though it's a holiday) the

__first real__

*WeBWorK*

__problem set__HW1 will "open" -- meaning that you can start working on it. When you're ready, you should open HW1 and print out a copy for yourself to work on until you're ready to submit answers. There will probably be about 15 problems, so start early.

When you enter answers for some or all problems,

*WeBWorK*will tell you whether you're right or wrong. If a solution is wrong, you can try the problem again and resubmit an answer as many times as you like up until the HW1 deadline at 5 p.m. on the following Monday, September 13. At that time, HW 1 will be automatically close online and HW 2 will open up a few minutes later.

The usual pattern for

*WeBWorK*assignments throughout the semester will be "Assignment opens Monday, and solutions are due by 5pm the following Monday, at which time the next assignment opens online." The Daily Assignments page will remind you of the dates. Problem set will usually contain about 15 problems for the week.

Each question will be worth 1 point. At the end of the semester, your total

*WeBWorK*points will be converted to a percentage = your WEBSCORE, and WEBSCORE will count for 10% of your grade in the course.
