Answer Format Help Links
This PG code shows how to add answer format help links to problems.
| PG problem file | Explanation |
|---|---|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "parserImplicitPlane.pl", ); TEXT(beginproblem()); |
Initialization:
We need to include the macros file |
Context("ImplicitPlane")->variables->are(x=>"Real",y=>"Real");
$answer = ImplicitPlane("x+y=2");
|
Setup:
By declaring there are only two variables, |
BEGIN_TEXT
Enter an equation for a line through the points
\( (0,2) \) and \( (2,0) \).
$BR
$BR
\{ ans_rule(20) \}
\{ AnswerFormatHelp("equations") \}
END_TEXT
|
Main Text:
We use
It is possible to change the link text by including a second argument to the routine: \{ AnswerFormatHelp("logarithms","click here for help entering logarithms") \}
|
$showPartialCorrectAnswers = 1; ANS( $answer->cmp() ); ENDDOCUMENT(); |
Answer Evaluation: As is the answer. |
