Question: Different output for function definition

 

f := x -> exp(-x)*sin(x); intvx:= 0..3;
f := proc (x) options operator, arrow; exp(-x)*sin(x) end proc
intvx := 0 .. 3

 

And this one below ( i prefer this one ) , but got in worksheet now the one above
Probably a option issue ?

 

 

f := x -> exp(-x)*sin(x); intvx:= 0..3;

proc (x) options operator, arrow; exp(-x)*sin(x) end proc
