Answer is an Equation Defining a Function
This PG code shows how to check student answers that are equations that define functions. If an equation defines a function, it is much more reliable to use the this method of answer evaluation (via parserAssignment.pl) than the implicit equation method (via parserImplicitEquation.pl)

| PG problem file | Explanation |
|---|---|
|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "parserAssignment.pl", ); TEXT(beginproblem()); |
Initialization:
We need to include the macro file |
Context("Numeric")->variables->are(x=>"Real",y=>"Real");
parser::Assignment->Allow;
parser::Assignment->Function("f");
$eqn = Formula("y=5x+2");
$fun = Formula("f(x)=3x^2+2x");
|
Setup: We must allow assignment, and declare any function names we wish to use. For more details and examples in other MathObjects contexts, see parserAssignment.pl |
Context()->texStrings;
BEGIN_TEXT
Enter \( y = 5x+2 \) \{ ans_rule(20) \}
$BR
$BR
Enter \( f(x) = 3x^2+2x \) \{ ans_rule(20) \}
END_TEXT
Context()->normalStrings;

Main Text: The problem text section of the file is as we'd expect. |
$showPartialCorrectAnswers = 1; ANS( $eqn->cmp() ); ANS( $fun->cmp() ); |
Answer Evaluation: As is the answer. |
