Is there an easy way to evaluate differential expressions for various functions? For example, if I have D[f[x],x]^2+f[x] in Mma, I'd like to evaluate it for various functions f[x]. This can be done via naming the expression and then letting f[x_]=<desired fn of x> and typing the expressions name upon which its evaluated - but this seems awfully clumbsy! Any suggestions? Thanks.
