Panic Button for Answer Hints with a Penalty

This PG code shows how to implement a panic button for answer hints with a penalty.

PG problem file	Explanation
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "problemPanic.pl", ); TEXT(beginproblem());	Initialization: We need to include the macros file `problemPanic.pl`.
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 `Panic::GradeWithPenalty();` after installing a problem grader. The `avg_problem_grader` is the default, which is why we commented out its installation. If we were to use a different problem grader, we would need to uncomment and modify this line of code.
