Defining a function from $ \mathbb {R}$p to $ \mathbb {R}$

For p = 1, e.g. for f  :  (x) $ \rightarrow$ x*sin(x), input :
f(x):=x*sin(x)
Or :
f:=x->x*sin(x)
Output :
(x)->x*sin(x)
If p > 1, e.g. for f  :  (x, y) $ \rightarrow$ x*sin(y), input :
f(x,y):=x*sin(y)
Or :
f:=(x,y)->x*sin(y)
Output :
(x,y)->x*sin(y)
Warning !!! the expression after -> is not evaluated. You should use unapply if you expect the second member to be evaluated before the function is defined.
