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? -r. kline rvk at blink.att.com
