What does cotangent mean?
MDRT organises yearly meetings and conferences conducted around the world. And some lucky high-achieving agents get sponsored by their agencies to go, which also means they get to squeeze in some travel, too. So, where and when are the next MDRT events happening?
Is cotangent even or odd?
The secant is the reciprocal of the cosine function, the cotangent is the reciprocal of the tangent function, and the cosecant is the reciprocal of the sine function. The six trigonometric functions can be found from a point on the unit circle. Cosine and secant are even; sine, tangent, cosecant, and cotangent are odd.
1. What is the Function of the Cotangent Formula?
Ans: The classical definition of the cotangent function is ‘the cotangent angle of the right angle triangle shows the ratio of the length of the ad...
2. What is Cotangent Ratio?
Ans: In general cot x formula is the reciprocal of the tan x formula. This means, the ratio of the adjacent side to the opposite side in a right tr...
3. What is Cotangent on a Calculator?

4. Why is cot 180 Undefined?
Ans: The value for cot 180 degree is undefined. Because the value for sine of a 180-degree angle is zero and the value for sine of a 180-degree ang...
What is the cotangent of a triangle?
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'.
What is tan -1?
For any x, tan -1(x) is the angle measure in the interval (- /2 , /2) whose tangent value is x. For any x, cot -1(x) is the angle measure in the interval (0 , ) whose cotangent value is x.
What is the definition of cotangent function?
Ans: The classical definition of the cotangent function is ‘the cotangent angle of the right angle triangle shows the ratio of the length of the adjacent side to the length of the opposite side of the right triangle’. This description is valid, only if the values of the right triangle are finite.
What is trigonometry in math?
What is Trigonometry? Trigonometry is the branch of mathematics that deals with the relationships between side lengths and angles of triangles. Usually, the triangles taken for trigonometry calculations are right-angle triangles. The trigonometric ratios are six. They are sine, cosine, tangent, cosecant, secant and cotangent ...
What is the tan angle in a right triangle?
The tan angle is the cot inverse formula.
Is the value of the cos angle divided by the sine angle undefined?
Ans: The value for cot 180 degree is undefined. Because the value for sine of a 180-degree angle is zero and the value for sine of a 180-degree angle is 1. So, the value of the cos angle divided by the sine angle is undefined.
What is Cotangent Formula?
For a given right triangle ABC as shown below, where A is an acute angle,
Is cot a reciprocal relationship?
Thus, we can say that the trigonometric ratios cot and tan has a reciprocal relationship among them.
Definition of Cotangent
In trigonometry, the cotangent is the reciprocal of the tangent. Cotangent is abbreviated as cot. The relation of cotangent and tangent is as follows: cot (θ) = 1⁄tan (θ) and cot (θ) = cos (θ)⁄sin (θ) and tan (θ) = 1⁄cot (θ)
Graph of the Cotangent Function
The image below is what y = cot (x) looks like when graphed for several periods. Notice how the curves are asymptotic to x = -π, x = 0, x = π, and so forth? This is because at every whole multiple of pi, the value of the function looks like:
