- course
- Sends a single ' - . 'grade back to the LMS. This grade is calculated out of the total question set that has been ' - . 'assigned to a user and made open. Therefore it can appear low, since it counts problem sets with ' - . 'future due dates as zero.
- homework
- Sends back a score for each problem set '
- . '(including for each quiz). To use this, the external links from the LMS must be problem set '
- . 'specific. For example,
webwork.myschool.edu/webwork2/course-name/problem_set_name. ' - . 'If the problem set name has space characters, they should be underscores in these addresses. ' - . 'Also, to initialize the communication between WeBWorK and the LMS, the user must follow each of ' - . 'these external learning tools at least one time. Since there must be a separate external tool link ' - . 'for each problem set, this option requires more maintenance of the LMS course.
Mode in which the LANG and DIR settings for a single problem are determined.
The system will ' - . 'set the LANGuage attribute to either a value determined from the problem, a course-wide ' - . 'default, or the system default, depending on the mode selected. The tag will only be added to ' - . 'the DIV enclosing the problem if it is different than the value which should be set in the main ' - . 'HTML tag set for the entire course based on the course language.
There are two options ' - . 'for the DIRection attribute: "ltr" for left-to-write scripts, and "rtl" for right-to-left ' - . 'scripts like Arabic and Hebrew.
The DIRection attribute is needed to trigger proper ' - . 'display of the question text when the problem text-direction is different than that used by the ' - . 'current language of the course. For example, English problems from the library browser would ' - . 'display improperly in RTL mode for a Hebrew course, unless the problen Direction is set to LTR.' - . '
The feature to set a problem language and direction was only added in 2018 to the PG ' - . 'language, so most problems will not declare their language, and the system needs to fall back ' - . 'to determining the language and direction in a different manner. The OPL itself is all English, ' - . 'so the system wide fallback is to en-US in LTR mode.
Since the defaults fall back ' - . 'to the LTR direction, most sites should be fine with the "auto::" mode, but may want to select ' - . 'the one which matches their course language. The mode "force::ltr" would also be an option for ' - . 'a course which runs into trouble with the "auto" modes.
Modes:
- "none" prevents ' - . 'any additional LANG and/or DIR tag being added. The browser will use the main setting which was ' - . 'applied to the entire HTML page. This is likely to cause trouble when a problem of the other ' - . 'direction is displayed.
- "auto::" allows the system to make the settings based on the ' - . 'language and direction reported by the problem (a new feature, so not set in almost all ' - . 'existing problems) and falling back to the expected default of en-US in LTR mode. ' - . '
- "auto:LangCode:Dir" allows the system to make the settings based on the language and ' - . 'direction reported by the problem (a new feature, so not set in almost all existing problems) ' - . 'but falling back to the language with the given LangCode and the direction Dir when problem ' - . 'settings are not available from PG.
- "auto::Dir" for problems without PG settings, this ' - . 'will use the default en=english language, but force the direction to Dir. Problems with PG ' - . 'settings will get those settings.
- "auto:LangCode:" for problems without PG settings, ' - . 'this will use the default LTR direction, but will set the language to LangCode.Problems with PG ' - . 'settings will get those settings.
- "force:LangCode:Dir" will ignore any setting ' - . 'made by the PG code of the problem, and will force the system to set the language with the ' - . 'given LangCode and the direction to Dir for all problems.
- "force::Dir" will ' - . 'ignore any setting made by the PG code of the problem, and will force the system to set ' - . 'the direction to Dir for all problems, but will avoid setting any language attribute for ' - . 'individual problem.

Hint
-A line representing a function slanting upwards to the right is increasing, since as you increase -the inputs, the outputs increase as well. -- If the line is horizontal then the outputs don't change -so the function is constant. -
-When you zoom in on most functions they look like straight lines. (The functions for which -this works are called differentiable functions --- there ARE functions which are not differentiable, -but we'll get to those later.) In any case you can tell whether a function is increasing or -decreasing by zooming in and determining whether the straight line is increasing or decreasing. -
-This means that the study of (differentiable) functions is largely a matter of understanding what -happens with straight line (or linear) functions. -
-
Remark on hints
-WeBWorK hints may or may not be helpful. - -Remember that WeBWorK's primary mission is to tell you whether your answer is correct. Programming -a computer to do this is hard enough, programming a computer to accurately understand why you -getting the wrong answer and to offer effective help is much harder. -
-
-If you are having trouble with a problem
-it is good to seek help from a human!
-This could be a fellow student, the TA or the professor. It is also helpful to look
-at the relevant chapter of the textbook. You can use the index to look up key words
-if you're not sure where to look.
-
Don't -waste too much time guessing at answers! -
-Read the book, your notes. Talk to someone! Print out a hard copy of the problem set -and take it down to the Pit to work on! - -
-You can use the Feedback button
-at the bottom of each problem page to send e-mail to the TA and to the professor.

-
-Your username is the same as the one used for your Union College
-email, and your initial password is your Union College Student ID
-number (you will change that after you log in).
-
-
-
-Log in and follow the instructions that will appear in this panel once
-you have done so. For the first assignment, do not log in as a
-guest user or using a friend's account. If you do, you will not
-receive credit for doing the asignment!
-
-
-
-On future assignments, you can use the guest accounts to get
-additional practice problems that are similar to the ones in your
-homework set, but with different numbers.

-Change Your Password
-
-
-
-If you haven't already changed your password, you should do so now.
-To do this, type your OLD password in the top box at the left and
-your NEW password in the two lower boxes at the left,
-then press the "Change User Options" button.
-
-
-
-Your password should be at least 6 characters long, and should include
-something other than just letters. Don't make it something that is
-easily guessed, and don't make it the same as the password for your
-e-mail account!
-
-
-
-If you prefer to receive your e-mail at a location other than your
-Union College account, you should change your e-mail address in the box
-at the left. Be aware, however, that your professor (and others on
-the Union campus) may still send mail to your Union College address,
-so you should check that account regularly anyway. Note that you can
-have your Union college e-mail forwarded to another address
-automatically if you wish.
-
-
-
-Finally, when you have made the changes that you want to make, select
-the "Homework Sets" link at the top of the red panel at the far left
-to get back to the list of homework sets.

-The $WW screen is divided into several areas, each used for a
-different purpose. You will need to understand these
-in order to use $WW effectively.
-$PAR
-
-At the upper left are the navigation buttons that allow you to move
-from problem to problem. The ${LQ}Next$RQ and ${LQ}Previous$RQ
-buttons, naturally, send you to the next and previous problems. The
-${LQ}Problem List$RQ button takes you back to the opening
-page for the homework set (the one that lists all the problems and
-gives the instructions for the homework set).
-$PAR
-
-The area below the navigation buttons is where $WW tells you about
-your score for the current problem. When you have submitted your
-answers, this is where you will be given information about what
-answers you got right and wrong. This
-area also shows you how many points a problem is worth.
-$PAR
-
-The main part of the page is the text of the problem you are trying to
-answer, including blank boxes for you to enter your answers. (There
-aren't any such boxes on this page, because you are not being asked
-any questions here, but usually there will be one or more answer blanks
-on a page.)
-$PAR
-
-Below the problem text is a message area where you may be informed
-about how partial credit is handled in multi-part problems. Other
-information also may appear there, such as a message indicating that
-the due date is passed, or that answers are available.

-##############################################

-
-The rules of precedence determine the order in which the mathematical
-operations are performed by $WW. It is essential for you to understand
-these so that you know how $WW interprets what you type in. If there
-are no parentheses and no functions (such as \{computer "sin"\} or
-\{computer "log"\}), then $WW computes the value of your answer by
-performing exponentiation first, followed by multiplication and division
-(from left to right), and finally addition and subtraction
-(from left to right).
-$PAR
-
-If there are expressions within parentheses, those expressions are
-simplified first. We'll talk about functions (and give a more
-complete list of rules) in a later problem.
-
-$PAR
-Examples:
-\{BeginList("UL")\}
-$ITEM
-\{student "4*3/6 = 12/6 = 2"\} (multiplications and divisions are done
-from left to right), and \{student "2*7 = 14"\}, so
-\{student "4*3/6-2*7+10 = 2 - 14 + 10 = -2"\}.
-$ITEM
-\{student "12/3/2 = 4/2 = 2"\} (multiplications and divisions are done
-from left to right).
-$ITEM
-\{student "12/(3/2) = 12/1.5 = 8"\}
-(expressions inside parentheses are calculated before anything else).
-$ITEM
-\{student "2*4${CARET}2 = 2*16 = 32"\} (exponentiation is done before multiplication),
-so \{student "2*4${CARET}2 - 3*4 = 2*16 - 3*4 = 32 - 12 = 20"\}.
-\{EndList("UL")\}
-$PAR
-
-To practice these rules, completely simplify the following
-expressions. Because the point of this problem is for you to do the
-numerical calculations correctly, $WW will only accept sufficiently
-accurate decimal numbers as the answers to these problems.
-It will not simplify any expressions, including fractions.

-Several types of parentheses are allowed: \{student "()"\},

-parentheses inside other parentheses, try using a different type for
-each so that you can see more easily which ones match up.
-$ITEMSEP
-
-$ITEM
-When you type a left parenthesis, type the corresponding right
-parenthesis at the same time, then position your cursor between them and
-type the expression that goes inside. This can save you a
-lot of time hunting for mismatched parentheses.
-$ITEMSEP
-
-$ITEM
-When you have a complicated answer, type a template for
-the structure of your result first. For example, suppose that you are
-planning to enter the fraction
-\[\frac{2x^2-5}{(x+1)(3x^{3x} - 22)}.\]
-A good way to start would be to type in \{student "()/[()*()]"\}.
-This shows a template of one number divided by the product of two
-other numbers. (Note that \{student "()/()*()"\} would not be a good
-way to start; do you see why?) Now when you fill in the expressions, you
-will be sure your parentheses balance correctly.

-
-Although $WW understands that numbers written next to each other are
-meant to be multiplied (so you do not have to use \{student "*"\} to

-When division or exponentiation are involved, it is a good idea to

-thing (first divide 1 by 2, then multiply the result by x), but the
-second makes it easier to see what is going on. Likewise, use
