Vertical Line Test On a graph, the idea of single valued means that no vertical line ever crosses more than one value If it crosses more than once it is still a valid curve, but is not a function Some types of functions have stricter rules, to find out more you can read Injective, Surjective and Bijective Infinitely Many My examples have just a few values, but functions usually work on .

Jul 12, 2002· An Archimedean spiral is, for example, generated while coiling a carpet A hyperbolic spiral appears as image of a helix with a special central projection (see diagram) A hyperbolic spiral is some times called reciproke spiral, because it is the image of an Archimedean spiral with an circle-inversion (see below) The name logarithmic spiral is due to the equation = ⁡

A logarithmic spiral, equiangular spiral, or growth spiral is a self-similar spiral curve that often appears in nature The first to describe a logarithmic spiral was Albrecht Dürer (1525) who called it an "eternal line" ("ewige lini") More than a century later, the curve was discussed by Descartes (1638), and later extensively investigated by Jacob Bernoulli, who called it Spira mirabilis .

The most famous and beautiful examples of the occurrence of the Fibonacci sequence in nature are found in a variety of trees and flowers, generally asociated with some kind of spiral structure For instance, leaves on the stem of a flower or a branch of a tree often grow in a helical pattern, spiraling aroung the branch as new leaves form .
