Dear Group, It is a pleasure talk to you all again. My plain question is: I want to use some "exact" notation with Mathematica. For instance, I want to use variables like " p' " instead of "pline" (or something like that). Also I want to use P2 (with the 2 underlined). The last option works in some calculations but not in all of them (Why?). Finally I want to define f1[x] as a function with the 1 underlined(Why is not working?). Any enlightment on these subject are very welcome. Thanks, Alex
