loadMacros(

TEXT(beginproblem());

Initialization: 

Context("Numeric");

$specific = Formula("e^x");

$general = FormulaUpToConstant("e^x");

Setup: Examples of specific and general antiderivatives:

  • Specific antiderivatives: e^x, e^x + pi
  • General antiderivatives: e^x + C, e^x + C - 3, e^x + K

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. 

BEGIN_PGML
+ Enter a specific antiderivative for [` e^x `]: [____________]{$specific->cmp(upToConstant=>1)}

+ Enter the most general antiderivative for [` e^x `]: [____________]{$general}
