Hmm - De Moivre, I'll get back to ya....

Nixy Elimi-nistrator Staff member Dec 9, 2002 #66 No, not how I did it I broke it up into the 4th root of 16 * 4th root of -1 Then it was 2 * (-1)^0.25 That then becomes 2* ((-1)^0.5)^0.5 That is then 2 * (i)^0.5

Jeslek Banned Dec 9, 2002 #67 Nixy has it right. You don't have to use DeMoivre's Theorem... That isn't the right direction for this question anyways, battyboy

ipmoof New Member Dec 9, 2002 #68 Phew! I thought I knew something about maths then for a second. Back to being cool...
ipmoof New Member Dec 9, 2002 #72 Sorry, I was just annoyed because LL called me a battyboy for hating maths in retalliation for me calling him a battyboy for fooling around with guys.

ipmoof New Member Dec 9, 2002 #74 Thanks. Maths does suck big fat hairy donkey penis, though. It's a shame there isn't more art & music on my computer systems engineering course.

Nixy Elimi-nistrator Staff member Dec 10, 2002 #75 Well, I always said ti sucked big fat hairy donkey BALLS but it can suck the penis too. I bet the donkey would like that I have a Calculus exam tomorrow then I am done math until Jan6
