Math2.org Math Reference Tables License / Terms of Use

The "Non-commercial Use License (NUL)" concerning the use and distribution of the "Math Reference Tables" (MRT) component of Math2.org is under review. The pre-2001-04-07 NUL is still in effect for the MRT content distributed prior to 2001-04-07. Until the review is finished, the following more restrictive rules are in effect for MRT content distributed since 2001-04-07:

• MRT or any part or modification of it may NOT be sold, commercially distributed, noncommercially distributed to a wide audience (> 100 people per year), placed in a distributed commercial work, or posted at a public Internet address without explicit written consent from the Owner.^{1, 2, 3}
• Any redistribution (of all, part, or a modification) of MRT must include a prominent reference to the original Math2.org MRT web site (www.math2.org/tables). If the redistribution permits anything other than person use, then the redistribution must also include this MRT license statement unless explicit written consent to do otherwise is obtained from the Owner.
• Except as stated in this license agreement, any redistribution is not necessarily supported by Math2.org or any of its contributors. Redistributors may not suggest otherwise support by Math2.org or any of its contributors for those redistributions or derivative works that contain them.
• The pages, graphics, organization, source code, and object code of MRT are copyrighted by the Owner. The actual intellectual content (such as individual equations or mathematical concepts) is -- of course -- freely available public domain, meaning there are no restrictions. (I can't copyright the quadratic formula.)
• MRT are provided "as is" without warranty of any kind, either expressed or implied. Math2.org and the Owner are not responsible for damages of any kind including but not limited to use, modification, distribution, fitness for a particular purpose, or correctness of the MRT. As this site is undergoing ongoing development, Math2.org and the Owner do not guarentee the correctness of its content.
• This statement does not apply to MRT content available after the date in which a new license statement is made public.
