Not knowing if the result has       indert Int in it or not, so I am calling eval(result_of_solve, Int = int)       on every one.              But this does not work sometimes, as in the above case.              Is there a better way to handle this?              I wish there is a way to tell Maple not to       use Inert anything in its answers ! This is very       annoying.              thanks,              --Nasser              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
