Notes on embedding Sage into WW problems using the Sage cell server - May/June 2012

When passing functions to Sage, if the function is defined as a math object problems can occur since it can happen that none of

$f
$f->string()
$f->stringify()
$f->TeX()

return the orginal string used to define the function.

For example with the set up:

Context("Numeric");
$f = Compute("(x-(-2))*(x-2)*(x-4)");

then

$f->string()

produces[x-(-2)]*(x-2)*(x-4)

$f->TeX() produces\left(x-\left(-2\right)\right)\!\left(x-2\right)\!\left(x-4\right) $f->stringify() produces: [x-(-2)]*(x-2)*(x-4) in normalStrings \left(x-\left(-2\right)\right)\!\left(x-2\right)\!\left(x-4\right) in texStrings Possible solution: Use a construction like

$f_raw = "(x-(-2))*(x-2)*(x-4)";
$f = Compute($f_raw);
