I am having problems trying to figure out how to convert millimeters to cubic feet per minute. Could you please help me? Thank You Very Much For Your Time And Consideration. Sincerely, Linda lindasal@pacbell.net

Linda, mm is a unit of length, ft^3/min has units length^3/time. So, you can't convert from one to the other. You could convert mm to feet, for example, because they both have units of length. -Todd

i am a student of university from iran. please solve this equation:

                              $y''+3x^2y=6x^3+\sin(x^2)\,$


I'd like to post some problems in classical mechanics. How about that as a subject? SanJoser

Hi, i would like to offer you webhost for free, and ask you if we could post problems and exercises in Spanish (we were searching some web like this at spanish but not found, instead of openning a new one we could share information) (Please, contact me, i'm theNinjaBunny - www.theNinjaBunny.com or see my email from the user profile (not post here for spam reasons))

Do you just do maths problems? Because I do physics and a site like this for physics would be awesome. I find this site REALLY USEFUL for my math tutorials.

This really is a great site BUT it would be nice to see some more sections, or a page for user suggested sections Also it would be cool if we could try to publicise the site more. That way everyone benefits! Any ideas? Scottie 000 23:55, 26 November 2007 (MST)

We've got some spam issues--maybe block user CcdomRolac and others who seem to be either bots or spammers. Ascentury 22:29, 19 November 2008 (EST)
