Comment #22 on issue 1358 by wflynny: (e*f*e*f).subs(e*f,f*e+h) fails if
e*f is not commutative
http://code.google.com/p/sympy/issues/detail?id=1358
Assuming that those failed utilities\pytest.py tests are acceptable, I have
only a
couple more comments on this:
The tests for the chebyshev polynomials should include a simplify term:
def test_chebyshev():
assert chebyshevt(0, x) == 1
assert chebyshevt(1, x) == x
assert chebyshevt(2, x) == 2*x**2-1
assert chebyshevt(3, x) == 4*x**3-3*x
for n in range(1, 4):
for k in range(n):
z = chebyshevt_root(n, k)
+ assert simplify(chebyshevt(n, z)) == 0
for n in range(1, 4):
for k in range(n):
z = chebyshevu_root(n, k)
+ assert simplify(chebyshevu(n, z)) == 0
If that change is made, my new mul.py fails only 3 tests that I can see:
- test_issue953() - in sympy\integrals\tests\test_integrals
- test_heurisch_hacking() - in sympy\integrals\tests\test_risch
- test_heurisch_radicals() - in sympy\integrals\tests\test_risch
They all fail because they cannot decompose polynomials. I think this has
something
to do with the division problem I commented on earlier which I still
haven't fixed.
I've hit somewhat of a wall with it and if someone could check it out and
just give
some feedback, that'd be awesome.
