Just had some free time and thought i would come see how one of my "fun" questions was going. Only to find it was closed. Link is: http://www.gamedev.net/community/forums/topic.asp?topic_id=314549 Reason for closing was apparently school work. Were u bored and had nothing else todo? The question was not realted to homework, it was simply a question which came across me when i was revising trig. Assuming you read the question i thought it would be easy to see why i would post a question like that here. The reference to the school book was just to show what i had been taught. Im not going to repost the question, im not going to argue. I just wanted to raise the point that my post was clearly not homework, and by the way, even if it was i would think that kind of question would have been gladley acepted by this forum. Anyway apart from that, these forums have been great to me, and i thank you all. Cheers, Nick
