Problem tagging data

Problem tagging:

DOCUMENT();

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

TEXT(beginproblem());

Initialization:

Context("Numeric");

$f1 = Compute("cos(pi)");
$f2 = Compute("sin(pi/3)");

Context("Fraction-NoDecimals");

Context()->functions->disable("All");
Context()->functions->enable("sqrt");

$answer1 = Compute("-1");
$answer2 = Compute("sqrt(3)/2");

Setup:

Context()->texStrings;
BEGIN_TEXT
Enter your answers as simplified fractions.
