As far as I know, any equation with a trig function of the form Sin[x]=x, there is no symbolic solution. The same problem arises with Exp[x]=x, however there is a function for this one known as the ProductLog or tree function but no an elementary solution. I'm not an expert so someone correct me if I'm wrong.
