By default, Mathematica assumes that variables are complex-valued. Accordingly, the following expression does not simplify
In[1]:=
Cos[πn]+Sin[πm]//Simplify
Out[1]=
Cos[nπ]+Sin[mπ]
Assume that variables are integers:
In[2]:=
 | AssumeInteger |
Out[2]=
m∈&&n∈
The expression now simplifies:
In[3]:=
Cos[πn]+Sin[πm]//Simplify
Out[3]=
n
