Disabling Functions so Students Must Simplify Answers
This PG code shows how to disable all functions and restrict student answers to fractions.
- Download file: File:DisableFunctions1.txt (change the file extension from txt to pg when you save it)
- File location in NPL:

| PG problem file | Explanation |
|---|---|
|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "contextFraction.pl", ); TEXT(beginproblem()); |
Initialization: |
Context("Fraction-NoDecimals");
$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 re-enable the |
Context()->texStrings;
BEGIN_TEXT
Enter your answers as simplified fractions.

\( $f1 = \)
\{ ans_rule(20) \}
\{ AnswerFormatHelp("fractions") \}
$BR
