i want to use complex variable such as c[i_]=re[i]+I*im[i] then I get conj[c[i]] =re[i]-I*im[i] by stating conj[a_]:=complexexpand[conjugate[a]]; but now i am writing c[i_][t_]=re[i][t]+I*im[i][t] but i am not getting conj[c[i][t]]=re[i][t]-I*im[i][t] by stating conj[a_]:=ComplexExpand[Conjugate[a[i][t]]] is there any way of writing this thing? any help will be very much appreciated. regards, tarun
