I am trying to find what variables have zero as a coefficient and have
been unsuccessful. Here is what I tried:
I2=I.groebner_basis()
f=SR(I2[0])
g=f.coeff()
print g
0
print g=='0'
False
groebner_basis(), SR(), and coeff() work fine but I can't figure out
how to test it. Does any one know the correct procedure to test this?
