Sage is an open source, online symbolic mathematical system. Details on Sage can be found at http://www.sagemath.org .
For use within WebWork, a special "single-cell" version of Sage is located at http://sagecell.sagemath.org
## Template for calling Sage from within a WebWork pg file

## Sample problem embedding Sage in WW
## END_DESCRIPTION

loadMacros(

"sage.pl"
);
TEXT(beginproblem());
Context("Numeric");
####### Answers to check by WeBWorK go in the list below.
$ansList = List("(pi)");
####### Possible Upper WeBWorK text
Context()->texStrings;

This is where WeBWorK problem text above the sage cell goes.
END_TEXT
Context()->normalStrings;
#### Sage Cell Server
#### Paste your code below fixing @ and $
#### Store any answers to send back as a list using the function below.

$SageCode = <<SAGE_CODE;

record_answer((a))
SAGE_CODE
Sage(
SageCode=>$SageCode,
AutoEvaluateCell=>'true'
);
####### WeBWorK text display following the Sage cell
Context()->texStrings;
BEGIN_TEXT
When you are comfortable with the coefficients that you have chosen, press
the submit button below.
END_TEXT
Context()->normalStrings;
######### Answer Evaluation
$showPartialCorrectAnswers = 1;
NAMED_ANS( sageAnswer => $ansList->cmp );
ENDDOCUMENT(); # This should be the last executable line in the problem.
The example shows how to pass perl variables from the problem initialization into the sage block.
- TEXT(<<SAGE_CODE);
where << SAGE_CODE without single quotes is necessary. However, the Sage code will not execute if no variables are actually passed in. Since $ and @ within the Sage code are now interpreted by perl, all latex delimiters should be converted from $ signs to \ ( and \ ) pairs. Additionally, any @interact needs to be escaped and written as ~~@interact
If you are not passing any variables, use:
- TEXT(<<'SAGE_CODE');
where <<'SAGE_CODE' tells perl not to interpret variables. Sage code can then be pasted in verbatim without any need to convert formatting or escaping other characters.
