PG problem file  Explanation 

Problem tagging: 

DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "contextFraction.pl", ); TEXT(beginproblem()); 
Initialization: 
Context("FractionNoDecimals"); $f1 = Formula("cos(pi)"); $f2 = Formula("sin(pi/3)"); Context()>functions>disable("All"); Context()>functions>enable("sqrt"); $answer1 = Compute("1"); $answer2 = Compute("sqrt(3)/2"); 
Setup:
We choose a context that requires fractions as answers and does not allow decimals. After constructing the formulas involving trig functions, we disable all functions and reenable the 
Context()>texStrings; BEGIN_TEXT Enter your answers as simplified fractions. $BR $BR \( $f1 = \) \{ ans_rule(20) \} \{ AnswerFormatHelp("fractions") \} $BR $BR \( $f2 = \) \{ ans_rule(20) \} \{ AnswerFormatHelp("fractions") \} END_TEXT Context()>normalStrings;
