Hi,
Assuming[Element[t/2, Integers],
If[Element[t/2, Integers], x, y] // Simplify
]
or
Refine[
If[Element[t/2, Integers], x, y] // Simplify,
Element[t/2, Integers]
]
or
If[Element[t/2, Integers], x, y] // Simplify[#,
Element[t/2, Integers]] &
??
Regards
Jens

 Dear Mathematica users,

 I often get results like the following when I do
symbolic sums, in this
 case of a Sin[ ... ]:

 ... ... ... If[2/T Element Integers, x, y] ...
...

 Now I know that 2/T is an Integer. How can I
tell Mathematica that this
 is so, such that it removes the 'If'? It seems
that Assumptions don't
 work for sums.

 Kind regards,
 Hanspeter
