DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "parserFormulaUpToConstant.pl", ); TEXT(beginproblem());	Initialization:
Context("Numeric"); $specific = Formula("e^x"); $general = FormulaUpToConstant("e^x");	Setup: The specific antiderivative should mark correct answers such as e^x, e^x + pi, etc. The general antiderivative should mark correct answers such as e^x + C, e^x + C - 3, e^x + K, etc. The specific antiderivative is an ordinary formula, and we check this answer, we will specify that it be a formula evaluated up to a constant (see the Answer Evaluation section below). For the general antiderivative, we use the FormulaUpToConstant() constructor provided by parserFormulaUpToConstant.pl.
Context()->texStrings; BEGIN_TEXT Enter a specific antiderivative for \( e^x \): \{ ans_rule(20) \} \{ AnswerFormatHelp("formulas") \} $BR $BR Enter the most general antiderivative for \( e^x \): \{ ans_rule(20) \} \{ AnswerFormatHelp("formulas") \} END_TEXT Context()->normalStrings;	Main Text:
$showPartialCorrectAnswers = 1; ANS( $specific->cmp(upToConstant=>1) ); ANS( $general->cmp() );	Answer Evaluation: For the specific antiderivative, we must use upToConstant=>1, otherwise the only answer that will be marked correct will be e^x.
