Folks, I'm a new user of Mathematica and am unable to get a full numerical evaluation of the Sqrt function in one case. Following are the input and output lines of the case giving me trouble. In[]:= a=2; b=2; c=2; d=2; e=2; f=2; g=Sqrt[(a+b)^2 + (c+d)^2 + (e+f)^2] Out[]= Sqrt[32. + 16. ] I've tried appending //N and inclosing the function in N[], but the result is the same. I'd be grateful for any pointers, Please respond directly to me at <lindell at arl.mil>. Thanks, Dennis ==== [MESSAGE SEPARATOR] ====
