Has anyone else noticed posts going missing on these pages? Like you click on an item in your watch list by UserXXXX, and it aint there? Im posting this msg on all ref desks.-- Light current 11:27, 1 October 2006 (UTC)
If i have the expression: x(x-2)/3x(x-1) Can I cancel the 2 x's out and turn the expression into: x-2/2x(x-1)? Why or why not? Jamesino 17:54, 1 October 2006 (UTC)
Ah ok thanks. Using your explanation i figured that X also cannot equal 1, -2, or 2. Jamesino 18:48, 1 October 2006 (UTC)
I have been using the Calculus Wikibook to teach myself derivative calculus. I get the derivative of to be equal to . Is this correct? If not, what is the correct answer? Thanks. --

:::Thanks, I forgot about that. That's what you get for typing a question in a hurry. By the way, can anyone help me with finding the correct derivative of ? Can you tell me what is it and how you get it? I can't even get the first demonstration to equal to what I work out now! That's what you get for reading stuff like that late at night wen you should really be in bed. I've just realised now I've spent more words talking off the track than on it. I think I better stop now. Thanks in advance. --

If I have some n-dimensional plane (a1*x1 + a2*x2 .... = 0) (a's are constants, x's are variables) that passes through the origin, how can I determine if the plane intersects with a corner of the n-dimensional cube defined by ( 0 <= x1,x2 ... <= 1). Thanks for any help with this problem, the only thing I've found is trying the co-orindate of each corner into the plane equation. I'm looking for something more effecient than that. Thanks again.
