   I tried an example in FriCAS. But I am newbie in it, so there   
   might be different way. Only way I know to tell Fricas   
   that n is integer (or positive integer) is this syntax:   
      
   n : PositiveInteger   
      
   But now FriCAS will not integrate!   
      
   integrate(exp(n*%i*x), x=0..2*%pi)   
      
       n is declared as being in PositiveInteger but has not been given a   
          value.   
      
   So I do not know how to tell Fricas to "assume" n is   
   a positive integer? Does FriCAS has assumptions other than   
   just saying  n: Integer or n: PositiveInteger and so on?   
      
   I googled and not able to find this information about FriCAS.   
      
   CAS will be limited if one can not use assumptions?   
      
   The above integrate will only work if   
      
   n : Symbol   
      
   May be a FriCAS expert knows how to do this in Fricas.
