Comment #11 on issue 2104 by matt...@gmail.com: canonical ordering of terms http://code.google.com/p/sympy/issues/detail?id=2104 I fixed this in a35aed24bd016b3fd0e4d51113373f6f33530542, so workarounds won't be necessary anymore, e.g.: In [1]: latex(x**2 + 1, order='lex') Out[1]: x^{2} + 1

Re: Issue 2104 in sympy: canonical ordering of terms

Comment #10 on issue 2104 by asmeurer: canonical ordering of terms http://code.google.com/p/sympy/issues/detail?id=2104 That should be a workaround for single variable polynomials, but this still needs to be fixed, because there is more to the various orderings than just reversing the order

Re: Issue 2104 in sympy: canonical ordering of terms

Comment #9 on issue 2104 by justin.y...@gmail.com: canonical ordering of terms http://code.google.com/p/sympy/issues/detail?id=2104 My mistake. I had defined a shortcut function to automatically set the 'descending' flag. What I meant was the following: Python 2.7.0 console for SymP

Re: Issue 2006 in sympy: functor objects

Comment #2 on issue 2006 by asmeurer: functor objects http://code.google.com/p/sympy/issues/detail?id=2006 I would expect this to also replace sin(2*x)**2 + cos(3*x)**2. No, because that doesn't equal (sin**2 + cos**2)(x) for any x, exactly or inexactly (and of course we only consider exact

Comment #24 on issue 1735 by smi...@gmail.com: Rename .func attribute (.args too?) http://code.google.com/p/sympy/issues/detail?id=1735 It's generic in the sense that a func has args (and there is function for Integrals to get the function contained in the "func"). But what about cls?, ob

Comment #23 on issue 1735 by ronan.l...@gmail.com: Rename .func attribute (.args too?) http://code.google.com/p/sympy/issues/detail?id=1735 'func' isn't generic enough. It doesn't work well for objects like Tuple, Add or Integral which don't map to mathematical functions. It's even mislea

Re: Issue 2006 in sympy: functor objects

Comment #1 on issue 2006 by Vinzent.Steinberg: functor objects http://code.google.com/p/sympy/issues/detail?id=2006 I like this idea, but I'm not sure about the proposed behavior. expr.subs(sin**2 + cos**2, 1) I would expect this to also replace sin(2*x)**2 + cos(3*x)**2. (f + id(1))(x, y)

Comment #10 on issue 835 by smi...@gmail.com: limit((5**x+3**x)**(1/x), x, oo) TODO http://code.google.com/p/sympy/issues/detail?id=835 The problem stems from this, I believe: h[2] >>> limit((1/x)/(1/x)**log(3),x,0) # should be 0 oo h[2] >>> limit((1/x)/(1/x)**Rational(3,2),x,0)
