 Author Comment/Response Bill Simpson 09/14/12 03:31am In Response To 'Re: Re: Re: Re: Re: Re: Re: Collecting terms in...'---------In your verbal description you give this problem: In[1]:= expr=Exp[a Fx[1]^2+a Fy[1]^2+a Fz[1]^2+b Fx[2]^2+b Fy[2]^2+b Fz[2]^2+c Fx[3]^2+c Fy[3]^2+c Fz[3]^2]; expr//.v_*Fx[c_]^2+v_*Fy[c_]^2+v_*Fz[c_]^2->v*F[c]^2 Out[2]= E^(a*F[1]^2 + b*F[2]^2 + c*F[3]^2) and that gives the answer you describe. In your image you give: In[3]:= expr=Exp[-1/2 x[1]^2- x[2]^2/3-x[3]^2/4-y[1]^2/2-y[2]^2/3-y[3]^2/4-z[1]^2/2-z[2]^2/3-z[3]^2/4]; expr//.v_*x[c_]^2+v_*y[c_]^2+v_*z[c_]^2->v*F[c]^2 Out[4]= E^(-1/2F[1]^2 - F[2]^2/3 - F[3]^2/4) URL: ,
