Other terms encountered include extreme and mean ratio, medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut, golden number, and mean of Phidias. In this article the golden ratio is denoted by the Greek lowercase letter phi (), while its reciprocal, or, is denoted by the uppercase variant Phi (). The figure on the right illustrates the geometric relationship that defines this constant. Expressed algebraically: This equation has one positive solution in the set of algebraic irrational numbers: At least since the Renaissance, many artists and architects have proportioned their works to approximate the golden ratio-especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio-believing this proportion to be aesthetically pleasing (see Applications and observations below). Mathematicians have studied the golden ratio because of its unique and interesting properties. The golden ratio is also used in the analysis of financial markets, in strategies such as Fibon...
