PG problem file | Explanation |
---|---|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "problemPanic.pl", ); TEXT(beginproblem()); |
Initialization:
We need to include the macros file |
Context("Numeric"); $answer = Real("sin(pi/3)"); |
Setup: Everything is standard |
BEGIN_TEXT \( \sin(\pi/3) \) = \{ ans_rule(10) \} $PAR \{ Panic::Button(label => "Request a Hint (25% Penalty)", penalty => .25) \} END_TEXT if ($panicked) { BEGIN_TEXT $PAR ${BBOLD}Hint:${EBOLD} The answer is greater than \( 1/2 \). $PAR \{Panic::Button(label => "Another Hint (25% Penalty)", penalty => .25)\} END_TEXT # if you want a secondary hint if ($panicked > 1) { BEGIN_TEXT ${BBOLD}Hint:${EBOLD} The answer is greater than \( \sqrt{2}/2 \). END_TEXT } } |
Main Text: We can construct a hint button that has a penalty associated with it. |
$showPartialCorrectAnswers = 1; # install_problem_grader(~~&avg_problem_grader); Panic::GradeWithPenalty(); ANS( $answer->cmp() ); ENDDOCUMENT(); |
Answer Evaluation:
We must issue the command |
