Symbolic limit calculation, numeric value desired

I am trying to calculate a limit operation of a function inside. Here is what I did: x = 0; f = (cos(x)*cos(h/2)*sin(h/2))/(h/2) - (sin(x)*sin(h/2)*sin(h/2))/(h/2); limit(f,h,0) ans = 1 limit(f,h,1) ans = 2*cos(1/2)*sin(1/2) I want to see what the numeric value of 2*cos(1/2)*sin(1/2) is. How do I obtain this value?
