| PG problem file | Explanation |
|---|---|
|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "parserSolutionFor.pl", "AnswerFormatHelp.pl", ); TEXT(beginproblem()); |
Initialization:
We must load |
Context("Vector");
$r = random(3,6,1);
$answer = SolutionFor("x^2+y^2+z^2=$r^2", [$r,0,0] );
|
Setup:
We use |
Context()->texStrings;
BEGIN_TEXT
A solution to the equation \( $answer->{f} \)
is \( (x,y,z) = \)
\{ ans_rule(20) \}
\{ AnswerFormatHelp("points") \}
END_TEXT
Context()->normalStrings;
|
Main Text:
To print the formula in the MathObject, we use |
$showPartialCorrectAnswers = 1; ANS( $answer->cmp() ); |
Answer Evaluation: |
Context()->texStrings;
BEGIN_SOLUTION
${PAR}SOLUTION:${PAR}
Solution explanation goes here.
END_SOLUTION
Context()->normalStrings;
COMMENT('MathObject version.');
ENDDOCUMENT();
|
Solution: |
