just to fill the void:

1.
We could rename the functions: tan->Tan,... etc.
(I don't like this. It's cowardice.)

2.
We could write some pre-processor definitions like
#define sin GiNaC::sin
...
(Well, maybe. These definition could be packed in a convenience header 
for the user like #include <GiNaC/GiNaC_with_cmath>. But better not to 
include this header multiple times ...)

3.
Don't avoid the ambiguities and force the user to explicitly write the 
namespace for such functions (and make lots of comments about it in the 
manual/tutorial).
(Yes, use the force! Maybe give the user some extra header like in 2. to 
ease the situation).

Jens
