http://code.google.com/p/sympy/issues/detail?id=3702
Just noting that in the case of a Matrix, we have applyfunc
Matrix(2,2,[a,b,c,d])
[a, b]
[c, d]
_.applyfunc(sin)
[sin(a), sin(b)]
[sin(c), sin(d)]

We can not simplify the formula for tan(z):
In [47]: 8*z/(pi**2-4*z**2) * hyper([1, S.Half-z/pi, S.Half+z/pi],

We can get an answer by substituting the pi away:
In [67]: _.subs(pi, t)
Out[67]: 8*z*hyper((1, 1/2 - z/t, 1/2 + z/t), (3/2 - z/t, 3/2 + z/t),
1)/(t**2 - 4*z**2)

A number of people have asked about graph theory in sympy in the past.
Our feeling is that with the high quality of NetworkX, it doesn't
make sense to reinvent graph theory in sympy. Maybe talk to the
NetworkX folks about doing a GSoC with them?
