Comment #4 on issue 3970 by avichal....@gmail.com: A bug on the degree
function
http://code.google.com/p/sympy/issues/detail?id=3970
Currently the degree() function converts the expression into a polynomial
class and then calls the class' degree method.
I was thinking of the following ways to solve this:-
1) Before converting to polynomial class, check if the expression is a
constant and return the answer there only.
OR
2) Add a default generator say x if the expression is a constant and then
convert it into a polynomial.
However there is a test which checks that it should raise an error if no
generators are provided for constant expression.
Any suggestions?
