Tax Deduction and Collection Account Number. In India, a Tax Deduction and Collection Account Number ( TAN) is a 10 digit alpha-numeric number issued by the Income Tax Department to the persons who are required to deduct or collect tax on payments made by them under the Indian Income Tax Act, 1961.

A transaction authentication number ( TAN) is used by some online banking services as a form of single use one-time passwords (OTPs) to authorize financial transactions. TANs are a second layer of security above and beyond the traditional single-password authentication . TANs provide additional security because they act as a form of two-factor ...
A U.S. Army National Guardsman's Geneva Conventions Identification Card from 2001, with social security number redacted. A United States Uniformed Services Privilege and Identification Card (also known as U.S. military ID, Geneva Conventions Identification Card, or less commonly abbreviated USPIC) is an identity document issued by the United States Department of Defense to identify a person as ...
Tantalum nitride (TaN) is a chemical compound, a nitride of tantalum. There are multiple phases of compounds, stoichimetrically from Ta 2 N to Ta 3 N 5, including TaN. As a thin film TaN find use as a diffusion barrier and insulating layer between copper interconnects in the back end of line of computer chips. Tantalum nitrides are also used in ...
de Moivre. Euler. Fourier. v. t. e. 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 trigonometric function are periodic functions, and their primitive period is 2π for the sine and the cosine, and π for the tangent, which is increasing in each open interval (π/2 + kπ, π/2 + (k + 1)π). At each end point of these intervals, the tangent function has a vertical asymptote .
The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 90°. [1] In the table below, the label "Undefined" represents a ratio If the codomain of the trigonometric functions is taken to be the real numbers these entries ...
Another precarious convention used by a small number of authors is to use an uppercase first letter, along with a “ −1 ” superscript: Sin −1 (x), Cos −1 (x), Tan −1 (x), etc. Although it is intended to avoid confusion with the reciprocal, which should be represented by sin −1 (x), cos −1 (x), etc., or, better, by sin −1 x, cos ...
