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(); |
