• With the number of recent threads from brand new users that we have observed in our Classifieds forum selling goods under questionable circumstances, we have instituted a new policy restricting new members of iLounge from posting new threads in the Classifieds forum until they have reached "Regular Member" status.

    New users become Regular Members once they have made 10 posts and been a member of the iLounge Forums for at least 7 days. Prior to this time, members may still read the Classifieds forum, and even respond to existing threads for items being sold by other members, but they may not create new threads advertising their own items for sale.

    This will hopefully help to protect our user community by discouraging fraudulent users from signing up and posting classified ads without having at least a very basic level of established membership in our forums.

    Obviously all users should still exercise due diligence when making use of our classifieds forums, but we hope that this restriction will help to decrease the number of blatantly fraudulent ads that we have been seeing in recent weeks.

    Please be sure to review our Classified Forum Policy for more information.

impssible maths!

Y=2x³-9x²+12x+8

find the co-ordinates of the stationary points and determine their nature...


the nature of the stat points don't work!


or is it jsut me.

y"=12x-18

and the stat points are (1,13) (2,12) it's obvious that (1,13) is concave down, but the calclus says no!

In all of the stat points that I have ever done, I never used the second derivative - it is not needed and just confuses the matter.

Ya, I seem to be getting a lot of that. I was able to re-create the old one, maybe I'll swap them back out. It will just be better quality than the old one was....

EDIT: Hows that?

Well, that's just a larger better quality of the old one. Obviously you were not paying attention.

HERE is the one had a up a bit ago that you did not like....and HERE is the original old one...

For the sake of not derailing this thread any further, I choose not to reply.

Oh, wait....Yep, my mistake, it's all good now.
