Sorry, I must have tried in the git version, not 0.7.6. I see the same
thing in 0.7.6, but it works fine in the git master.

excited about csympy project and wondering if I could contribute to it as
this year's GSoC project?

The sparse representation is efficient when there are many variables. PR

Dear all,
I am interested in doing a small thing (perhaps).
I wish to have an 'indexed function'
The purpose would be to have something like
**
f = symbols('f', cls=IndexedFunction)
i = Idx('i')
That is true that if you can replace indexes with a multiple argument
function. But an index is an integer not a real.
Furthermore the feature that makes indexed quantity behave just like a
numpy array is neat.
I think that when you manipulate a tensor/matrix field it would be nice be

Hi,
I found another error limit :
If x = symbols('x', positive=True), limit(tan(abs(x))/acosh(x), x, pi/2,
'-') returns oo -- OK
If x = symbols('x', real=True), limit(tan(abs(x))/acosh(x), x, pi/2, '-')
returns oo*sign(1/Subs(Derivative(re(_x), _x), (_x,), (0,))) !!
I guess the first result is

Hello.
Maybe, it could be useful to have a abssimplify method that will try to
simplify abs expressions.

I haven't studied all the notes prior to this, but it may be helpful to
look at Macsyma/ Maxima.
Series can be extended to several variables in different ways, e.g.
series in x to order xn with coefs as series in y to order yn etc
or to total order that is degree in(x) + degree in (y) +
