benbuks: guys ..i made mistake in that abelian question We should overlook this now, it's been fun solving calculus with great minds here and also learning at the same time. Big congrats to the winner (Drniyi4u) and all the other participants. Thanks to you, benbuks, as well for the time you've put into this. |
