You could try
x,y = var(x,y)
dy_dxB(x,y) = cos(x) - sin(x) - y
eulers_method(dy_dxB,0,2,0.1,3)
but I don't know why Sage will not evaluate the cos and
sin terms, so you end up with a long messy hybrid
symbolic/numberical expression.
If you use instead
eulers_method(dy_dxB,0,2,0.1,3,
Just a guess: your system is non-linear and that causes a problem somehow.
If you modify the linear terms you get

I'm a bit confused by your question. If you mean k-th roots of unity in
the complex

Of these two examples:

The first returns an error unable to convert x (=x) to an integer.
Can anyone explain what's going on here?
I think the first tries to use Sage's symbolic

give you what you want.

I'm not sure if this helps, but you can create a polynomial
of the type you want a bit simpler:
sage: var(x,y)
(x, y)
sage: Inds = CartesianProduct(range(5), range(4))
sage: sum([var(a+str(i)+str(j))*x^i*y^j for i,j in Inds])
