GraphSketch Flash Applet Sample Problem 3
Flash Applets embedded in WeBWorK questions GraphSketch Example
Sample Problem with graphSketch.swf embedded
This sample problem shows how to use this versatile applet.
A standard WeBWorK PG file with an embedded applet has six sections:
 A tagging and description section, that describes the problem for future users and authors,
 An initialization section, that loads required macros for the problem,
 A problem setup section that sets variables specific to the problem,
 An Applet link section that inserts the applet and configures it, (this section is not present in WeBWorK problems without an embedded applet)
 A text section, that gives the text that is shown to the student, and
 An answer and solution section, that specifies how the answer(s) to the problem is(are) marked for correctness, and gives a solution that may be shown to the student after the problem set is complete.
The sample file attached to this page shows this; below the file is shown to the left, with a second column on its right that explains the different parts of the problem that are indicated above. A screenshot of the applet embedded in this WeBWorK problem is shown below:

##DESCRIPTION ## understanding derivatives graphically ##ENDDESCRIPTION ##KEYWORDS('derivatives', 'graph','Flash applets','NSF0941388') ## DBsubject('Calculus') ## DBchapter('Limits and Derivatives') ## DBsection('Derivatives') ## Date('6/12/2012') ## Author('Barbara Margolius') ## Institution('Cleveland State University') ## TitleText1('') ## EditionText1('2012') ## AuthorText1('') ## Section1('') ## Problem1('') ########################################### # This work is supported in part by # the National Science Foundation # under the grant DUE0941388. ########################################### 
This is the tagging and description section of the problem. Note that any line that begins with a "#" character is a comment for other authors who read the problem, and is not interpreted by WeBWorK. The description is provided to give a quick summary of the problem so that someone reading it later knows what it does without having to read through all of the problem code. All of the tagging information exists to allow the problem to be easily indexed. Because this is a sample problem there isn't a textbook per se, and we've used some default tagging values. There is an online list of current chapter and section names and a similar list of keywords. The list of keywords should be comma separated and quoted (e.g., KEYWORDS('calculus','derivatives')). 
DOCUMENT(); loadMacros( "PGstandard.pl", "AppletObjects.pl", "MathObjects.pl", ); 
This is the initialization section of the problem. The first executed line of the problem must be the
The 
# Set up problem TEXT(beginproblem()); $showPartialCorrectAnswers = 1; Context("Numeric"); $ans =Compute("1"); $pos = 2; #don't care whether positive or negative $inc = 2; #function should be decreasing $cup = 1; #concave up $xval = 3.5; $yval = random(2,0,1); $boardMessage = "Sketch a function with positive second derivative through the point shown."; $showMM = 'true'; # don't display x and y ranges 
The graphSketch.swf applet will accept settings for whether the function is to be positive or negative, increasing or decreasing, or concave up or concave down. A setting of '1' indicates it must have this behavior, a setting of '0' indicates it must have the opposite of this behavior and a setting of '2' indicates that this behavior is not required.

################################### # Create link to applet ################################### $appletName = "graphSketch"; $applet = FlashApplet( codebase => findAppletCodebase("$appletName.swf"), appletName => $appletName, appletId => $appletName, setStateAlias => 'setXML', getStateAlias => 'getXML', setConfigAlias => 'setConfig', getConfigAlias => 'getConfig', maxInitializationAttempts => 5, # number of attempts to initialize applet answerBoxAlias => 'answerBox', height => '550', width => '550', bgcolor => '#ededed', debugMode => 0, submitActionScript => qq{getQE("answerBox").value=getApplet("$appletName").getAnswer() }, ); 
This is the Applet link section of the problem.
Those portions of the code that begin
the line with 
################################### # Configure applet ################################### #initialization data  problem setup # $pos  0 to require negative function # 1 to require positive function # 2 to not require the function to # be either positive or negative # $inc  0 to require decreasing function # 1 to require increasing function # 2 to not require the function to # be either increasing or decreasing # $cup  0 to require concave down function # 1 to require concave up function # 2 to not require the function to # be either concave up or concave down # the student can also be required to have the # curve go through one or two points. Syntax is # <pts><pt xval='1' yval='2' showIt='true'/></pts> # to display the point (1,2) and require the # function to go through it # # $boardMessage  instructions to # display in applet. # $showMM  displays x and y ranges. # Not usually needed. Might be # helpful if curve is to go through # particular points. 
You must include the section that follows 
$applet>configuration(qq{<xml> <pos>$pos</pos><inc>$inc</inc> <cup>$cup</cup> <boardMessage>$boardMessage</boardMessage> <showMM>$showMM</showMM> <bland>true</bland></xml>}); $applet>initialState(qq{<xml> <pos>$pos</pos><inc>$inc</inc> <cup>$cup</cup> <boardMessage>$boardMessage</boardMessage> <showMM>$showMM</showMM> <bland>true</bland></xml>});; TEXT( MODES(TeX=>'object code', HTML=>$applet>insertAll( debug=>0, includeAnswerBox=>0, ))); END_TEXT 
The lines

TEXT(MODES(TeX=>"", HTML=><<'END_TEXT')); <script> if (navigator.appVersion.indexOf("MSIE") > 0) { document.write("<div width='3in' align='center' style='background:yellow'> You seem to be using Internet Explorer. <br/>It is recommended that another browser be used to view this page.</div>"); } </script> END_TEXT 
The text between the 
BEGIN_TEXT $BR $boardMessage $BR Press 'score' to check your work. When it is correct, press 'submit answers'. $BR If your graph is close to correct (not much marked red) pressing the 'SMOOTH' button may help. END_TEXT Context()>normalStrings; 
This is the text section
of the problem. The

############################################################## # # Answers # ## answer evaluators NAMED_ANS('answerBox'=>$ans>cmp()); ENDDOCUMENT(); 
This is the answer
section of the problem. The applet returns a value of '1' if
the students sketch is close enough. The sketch will
appear in the applet with the incorrect areas marked in red.
The screenshot shows a correct sketch. The smooth button
was used to get the curve to be as smooth as it is. The screenshot
shows a partially drawn graph with xminimum and maximum values
displayed. The coordinate value of the location of the mouse is
shown. This is enabled when
