"In elementary algebra, a quadratic equation (from the Latin quadratus for "square") is any equation having the form
ax^2+bx+c=0
where x represents an unknown, and a, b, and c are constants with a not equal to 0. If a = 0, then the equation is linear, not quadratic. The constants a, b, and c are called, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.
Because the quadratic equation involves only one unknown, it is called "univariate". The quadratic equation only contains powers of x that are non-negative integers, and therefore it is a polynomial equation, and in particular it is a second degree polynomial equation since the greatest power is two.
Quadratic equations can be solved by a process known in American English as factoring and in other varieties of English as factorising, by completing the square, by using the quadratic formula, or by graphing." [Quadratic equation. Wikipedia]

This circular motion diagram sample was created on the base of the figure illustrating the article "Collaboration 2.0" from the HLWIKI International website. "Collaboration is an activity where individuals are motivated to work together in order to achieve certain mutually-desirable, articulated and achievable goals. In the digital age, collaboration 2.0 combines various aspects of web 2.0 and social media with the principles of collaboration. Some critical or typical features of collaboration 2.0 should include:
(1) synchronous collaboration via social calendaring, online meeting software and instant messaging tools,
(2) asynchronous collaboration made possible via shared workspaces and annotation capabilities.
A new form of collaboration is called collaborative information seeking which Wikipedia defines as "... a field of research that involves studying situations, motivations, and methods for people working in collaborative groups for information seeking projects, as well as building systems for supporting such activities. Such projects often involve information searching or information retrieval (IR), information gathering, and information sharing. Beyond that, CIS can extend to collaborative information synthesis and collaborative sense-making." " [hlwiki.slais.ubc.ca/ index.php/ Collaboration_ 2.0]
