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("FractionNoDecimals"); Context()>functions>disable("All"); Context()>functions>enable("sqrt"); $answer1 = Compute("1"); $answer2 = Compute("sqrt(3)/2"); 
Setup:
