PG Labs

On-line labs for rendering of PG code. These two labs allow you to experiment with PG syntax.

Test PG code fragments


For example:

$f = Compute("x^2-3x+5");
$fp = $f->D; # calculate the derivative
TEXT($fp->cmp->evaluate("2x-3")->pretty_print );
  • On the last line TEXT prints the results of (reading from left to right)
    • Constructing the AnswerEvaluator for the contents of the Formula $fp
    • Evaluating the string "2x-3" using this AnswerEvaluator to produce an AnswerHash
    • Recursively representing the contents of the AnswerHash in a nice table

Experimental PGML markup lab

  • Experiment with the new PG markup language syntax (PGML)] which simplifies the graphical layout

of the mathematics question. This is still under development and can't yet be used in standard PG problems.
