DOCUMENT();   

loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"parserSolutionFor.pl",
"AnswerFormatHelp.pl",
);     

TEXT(beginproblem());

Initialization: We must load parserSolutionFor.pl.

Context("Vector");

$r = random(3,6,1);

$answer = SolutionFor("x^2+y^2+z^2=$r^2", [$r,0,0] );

Setup: We use SolutionFor(equation, point) to define this MathObject. For more details and options, see the POD documentation

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 ->f.

$showPartialCorrectAnswers = 1;

ANS( $answer->cmp() );

Answer Evaluation:
