Inverse Trigonometric Functions
In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, antitrigonometric functions or cyclometric functions) are the inverse functions of the trigonometric functions (with suitably restricted domains). Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry. Notation Several notations for the inverse trigonometric functions exist. The most common convention is to name inverse trigonometric functions using an arc- prefix: , , , etc. (This convention is used throughout this article.) This notation arises from the following geometric relationships: when measuring in radians, an angle of ''θ'' radians will correspond to an arc whose length is ''rθ'', where ''r'' is the radius of the circle. Thus in the unit circl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attan
Attan ( ps, اتڼ) is a traditional dance originating from the tribal Pashtun regions of Afghanistan and North Western Pakistan. It is now considered the national dance of Afghanistan. Some believe it has spiritual roots connecting it to Zoroastrianism. Others link the dance to the British occupation and the Pashtun resistance movement, when Pashtuns used the dance to instil confidence and energy among warriors readying to battle the colonisers. The Attan was also conducted by Pashtuns in times of war or during weddings or other celebrations (engagements, weddings and informal gatherings). It is now considered the national dance of Afghanistan, popularly carried by other ethnic groups in Afghanistan as well as by the Pashtun ethnic group in Pakistan. The traditional Attan is a special type of dance performed by a troupe of Pashtun tribesmen who would wave swords ( Khattak tribe) or guns ( Mehsud tribe) oelr scarves in the air while drummers beat drums.
