Apache OpenOffice LaTeX/Mathematics One of the greatest motivating forces for Donald Knuth when he began developing the original TeX system was to create something that allowed simple construction of mathematical formulas, while looking professional when printed. The fact that he succeeded was most probably why TeX (and later on, LaTeX) became so popular within the scientific community. Typesetting mathematics is one of LaTeX's greatest strengths. It is also a large topic due to the existence of so much mathematical notation. If your document requires only a few simple mathematical formulas, plain LaTeX has most of the tools that you will need. or in the preamble of the document. Mathematics environments[edit] LaTeX needs to know beforehand that the subsequent text does indeed contain mathematical elements. As maths require special environments, there are naturally the appropriate environment names you can use in the standard way. The equation* and displaymath environments are functionally equivalent.

Google Search Operators The following table lists the search operators that work with each Google search service. Click on an operator to jump to its description — or, to read about all of the operators, simply scroll down and read all of this page. The following is an alphabetical list of the search operators. This list includes operators that are not officially supported by Google and not listed in Google’s online help. Each entry typically includes the syntax, the capabilities, and an example. Some of the search operators won’t work as intended if you put a space between the colon (:) and the subsequent query word. allinanchor: If you start your query with allinanchor:, Google restricts results to pages containing all query terms you specify in the anchor text on links to the page. Anchor text is the text on a page that is linked to another web page or a different place on the current page. allintext: allintitle: allinurl: In URLs, words are often run together. author: cache: define: ext: filetype: group: id: inanchor:

A Microsoft admitiu, em comunicado, que está "ciente de que alguns clientes estão tendo dificuldades depois de instalar o update de segurança KB2823324 do Windows 7", lançado na terça. "O problema está atualmente somente no Brasil e estamos trabalhando ativamente para resolvê-lo", completa o texto. A atualização KB2823324 também se aplica ao Windows Server 2008 e ao Windows Vista, mas nenhum usuário desses sistemas reclamou de problemas.
