Sorry for 'refreshing' this message but does anyone know if I can define the assumption below. I don't want to write specific assumptions for each term in Limit since I have many different variables and forms of a. Is it possible to generalise the assumption? it would really help me (and I really don't want to have to buy any additional maths software). timreh719 at yahoo.com.tw (bryan) wrote in message news:<ahdf97$i36$1 at smc.vnet.net>... > Hi All : > I am also interesting in the solution of how to make an asumption > in Mathematica.
