	A question about forming functions.  Suppose I create a series, using
	a=Normal[Series[Sin[x],{x,0,5}]]
	giving a = x - x^3/3! + x^5/5!.
	I now want to use a to create a function of x, which, functionally,
	is
	f[x_]:=a.
	This will not work in practice.  Is there a way to do this?  For
	something short, as in this example, I could just as well type 
	the expression
	f[x_]:= x - x^3/3! + x^5/5!
	and everything would work fine.
	What procedure would allow me to create the series and convert it
	to a function of the variable?
