contextLimitedPolynomial.pl - Allow only entry of polynomials.
Implements a context in which students can only enter (expanded) polynomials (i.e., sums of multiples of powers of x).
Select the context using:
If you set the "singlePowers" flag, then only one monomial of each degree can be included in the polynomial:
There is also a strict limited context that does not allow operations even within the coefficients. Select it using:
In addition to disallowing operations within the coefficients, this context does not reduce constant operations (since they are not allowed), and sets the singlePowers flag automatically. In addition, it disables all the functions, though they can be re-enabled, if needed.
