Diego, Use TraditionalForm. xc[i_] := (xn[i] + xn[i - 1])/2 deno = Factor[(xc[i + 1] - xc[i])] % // TraditionalForm David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Diego Luego [mailto:dluego at yahoo.es] To: mathgroup at smc.vnet.net Hello, I am wondering if it is possible to ask Mathematica the following: 1.- In the output below (Out[7]), instead of the Mathematica default arrangement of terms in the numerator, I would like to obtain xn[1 + i] - xn[i - 1]. In[6]:= xc[i_] := (xn[i] + xn[i-1])/2 In[7]:= deno = Factor[(xc[i+1] - xc[i])] -xn[-1 + i] + xn[1 + i] Out[7]= ----------------------- 2 2.- I would like to be able to tell Mathematica to show the answer of output Out[8] in the form Fc[1 + i] - Fc[i] ----------------------- xn[1 + i] - xn[i - 1] ----------------------- 2 In[8]:= a = (Fc[i+1] - Fc[i])/deno 2 (-Fc[i] + Fc[1 + i]) Out[8]= ----------------------- -xn[-1 + i] + xn[1 + i] Thanks for your help.
