Dactylic hexameter (also known as heroic hexameter and the meter of epic) is a form of meter or rhythmic scheme frequently used in Ancient Greek and Latin poetry. The scheme of the hexameter is usually as follows (writing – for a long syllable, u for a short, and u u for a position that may be a long or two shorts):
In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles .
The orange sheet in the middle is the principal sheet representing arctan x. The blue sheet above and green sheet below are displaced by 2 π and −2 π respectively. Since the inverse trigonometric functions are analytic functions , they can be extended from the real line to the complex plane.
The following outline is provided as an overview of and topical guide to trigonometry: Trigonometry – branch of mathematics that studies the relationships between the sides and the angles in triangles. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves.

Ordinary trigonometry studies triangles in the Euclidean plane .There are a number of ways of defining the ordinary Euclidean geometric trigonometric functions on real numbers, for example right-angled triangle definitions, unit circle definitions, series definitions [broken anchor], definitions via differential equations [broken anchor], and definitions using functional equations.
An example of dactylic meter is the first line of Henry Wadsworth Longfellow's epic poem Evangeline (1847), which is in dactylic hexameter: This is the / forest prim- / eval. The / murmuring / pines and the / hemlocks, The first five feet of the line are dactyls; the sixth a trochee.
