Sage in WeBWorK

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://sagemath.org:5467

To pass perl variables to the sage block if you need to from the problem initialization use:

TEXT(<<

SAGE_CODE

); Details on how to pass variables in to be added later ... under construction

where << SAGE_CODE allows interpolation

otherwise use:

TEXT(<<'

SAGE_CODE

');

where 'SAGE_CODE' tells perl not to interpolate variables
