What does cot mean in trigonometry?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .
What is cot ∠ a cot ∠ A )?
In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length of the side opposite the angle. The abbreviation is cot.
What is cotangent used for in math?
1 : a trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the leg opposite.
What is cot sec and csc?
Csc sec cot are the three trigonometric functions cosecant, secant, and cotangent respectively. These functions are also called the reciprocal trigonometric functions as they are the reciprocals of the sine function, cosine function, and tangent function, respectively.
What is the full form of cot?

When was cotangent invented?
The cotangent function is an old mathematical function. It was mentioned in 1620 by E. Gunter who invented the notation of “cotangens”.
Where is cotangent?
In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just ‘cot’.
Who discovered cotangent?
Habash al-Hasib al-Marwazi
Circa 830, Habash al-Hasib al-Marwazi discovered the cotangent, and produced tables of tangents and cotangents. Muhammad ibn Jābir al-Harrānī al-Battānī (853–929) discovered the reciprocal functions of secant and cosecant, and produced the first table of cosecants for each degree from 1° to 90°.
What is the representation of cotangent?
The cotangent function can be represented using more general mathematical functions. As the ratio of the cosine and sine functions that are particular cases of the generalized hypergeometric, Bessel, Struve, and Mathieu functions, the cotangent function can also be represented as ratios of those special functions.
What is cot the opposite of?
The cotangent ( cot ) (\cot) (cot) The cotangent is the reciprocal of the tangent. It is the ratio of the adjacent side to the opposite side in a right triangle.
What is COTS application?
Commercial-off-the-shelf (COTS) software is a term for software products that are ready-made and available for purchase in the commercial market. Public sector organizations are relying more and more on COTS applications to supplement, enhance or replace proprietary systems.
What is the symbol of cotangent?
function in trigonometry (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What is COT application?
What is a COTS solution?
COTS solutions are third-party solutions that are bought, licensed, or acquired; often, they are integrated into a larger system. COTS-based systems (CBS) are COTS solutions in which at least 50% of a system is based on a COTS product.
What is COT product?
A COTS (commercial off-the-shelf) product is one that is used “as-is.” COTS products are designed to be easily installed and to interoperate with existing system components.
What is cot in trigonometry?
What is cot in trigonometry. In trigonometry, cot or cotangent is one of six trigonometric ratios.
What is trigonometry in math?
Written By: Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What is cotangent in trigonometry?
In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just ‘cot’. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used.
What are the 6 trigonometric functions in trigonometry?
