Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less commonly used. It was mentioned in 1620 by E. Many trigonometric identities involve cotangent, such as the Pythagorean identity 1 + cot² θ = csc² θ. Illustrated definition of Cotangent: In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). Using Reference Angles to Evaluate Tangent, Secant, Cosecant, and Cotangent We can evaluate trigonometric functions of angles outside the first quadrant using reference angles as we have already done with the sine and cosine functions. Learn the definition, formula, and graph of the cotangent function, and how to find its inverse and derivative. Cotangent appears frequently in trigonometry courses, calculus (its derivative is −csc² x), and physics problems involving slopes or angular relationships. The four functions $\sin,$ $\cos,$ $\tan$ and $\cot$ are called the trigonometric functions. The classical definition of the cotangent function for real arguments is: "the 2 days ago · Calculus and Analysis Special Functions Trigonometric Functions Calculus and Analysis Calculus Integrals Definite Integrals History and Terminology Database Collections Integer Sequence Databases Online Encyclopedia of Integer Sequences Cotangent Download Wolfram Notebook Cotangent In the unit circle, the cotangent of an angle alpha is the reciprocal of the tangent, defined as the ratio of the cosine to the sine of angle alpha. Feb 10, 2026 · Learn all about Trigonometry from basics to advanced through this Trigonometry tutorial- [Read here!] Basic Trigonometric Ratios There are 6 ratios in trigonometry. The functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot). Learn the definitions, graphs and identities of sec, cosec and cot, trigonometric functions related to sin, cos and tan. Euler (1748) used this function and its notation in their investigations. There are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Introduction to the Cotangent Function Defining the cotangent function The cotangent function is an old mathematical function. See examples of cotangent of large and negative angles, and how to use a calculator for cotangent. Feb 24, 2025 · Trigonometric functions, also known as ‘ circular functions,’ are the ratio between any two sides of a right triangle: the opposite side, the adjacent side, and the hypotenuse with respect to a reference angle θ. Trigonometric Functions Trigonometric Graphs Trigonometric Identities Lessons On Trigonometry These lessons, with video lessons, examples and step-by-step solutions, help Algebra 2 students to learn about the trigonometric function: Sin, Cos, Tan and the reciprocal trigonometric functions Csc, Sec and Cot. Find out how to solve trigonometric equations involving these functions. Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. For a real angle , the sine and cosine give the vertical and horizontal Cartesian coordinates, respectively, of the corresponding point on the unit circle. These are referred to as Trigonometric Functions. What is Cot x formula? Cotangent is the reciprocal of tan, Cot x = Learn about trigonometric identities and their applications in simplifying expressions and solving equations with Khan Academy's comprehensive guide.

They admit geometric interpretations on the unit circle, exhibit periodic behavior, and play a fundamental role in trigonometry, analytic geometry, and the study of complex numbers. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant. A trigonometric equation is an equation involving one or more trigonometric ratios of unknown angles. It is the length that produces an angle where the cot of that angle is the length. It means that the relationship between the angles and sides of a triangle are given by these trig functions. Therefore, trig ratios are evaluated with respect to sides and angles. They describe rotation and everything that repeats periodically, such as waves, sound and alternating current. The law of cotangents describes the relationship between the lengths of the sides of the triangle and the cotangents of the halves of the three angles.

Cotangent's Inverse — cot -1 The inverse function of the cotangent is called arc cotangent. In a right triangle, the cotangent of an angle is the ratio between adjacent and the opposite sides. Gunter who invented the notation of "cotangens". So what is the cotangent? According to the picture above, the cot formula is: divide the side next to the angle by the other one. Here is what the relation looks like when used: cot (65°) = 0. This concept, in essence, is the idea behind trigonometry. $\mathrm{cot}\text{ }\alpha =\frac{1}{\mathrm{tan}\alpha }=\frac{\mathrm{cos}\alpha }{\mathrm{sin}\alpha }$ It is represented by the symbols cot, ctg, or cotg.
