Where on the unit circle is Cotangent undefined? Because the cotangent function is the reciprocal of the tangent function, the cotangent value will be undefined when the tangent value is zero, and zero when the tangent value is undefined. Click to see full answer.
When is the tangent of a circle undefined?
REcall that So, in this case, tangent is undefined whenever the denominator is zero. That is, when . Checking the unit circle with the interval , this restriction corresponds to the upper half of the unit circle. In this case, the x component of each point is cosine. We are interested at the points where . .
Is cotangent of tan x = 0 undefined?
Trigonometric functions are undefined when they represent fractions with denominators equal to zero. Cotangent is the reciprocal of tangent, so the cotangent of any angle x for which tan x = 0 must be undefined, since it would have a denominator equal to 0.
What is the cotangent of a circle?
The cotangent as a line segment of the unit circle Like the other trigonometric functions, the cotangent can be represented as a line segment associated with the unit circle. The diagram shows the cotangent for an angle of rotation θ of forty-five degrees (measured anti-clockwise from the positive x -axis).
How do you find cotangent?
To learn about cotangent, we must first review what a tangent is. The tangent function can be found by comparing the opposite side over the adjacent side. This is also viewed by comparing the sine over the cosine functions.
Why is the cotangent value undefined?

Is cot undefined at 0?
Notice, we have indeterminate form, so cot(0) is undefined.
Where does cot not exist?
cot θ will have no value at θ = 0 and θ = π. sin θ has no value. The trigonometric functions are functions only of the angle θ.
Why is cot 180 undefined?
...and note that the sine of a 180 degree angle is zero, and the cosine of that angle is -1. So, this evaluates to a division by zero. Therefore, cot180 is undefined.
For which value of is cot () undefined?
Cotangent is the reciprocal of tangent, so the cotangent of any angle x for which tan x = 0 must be undefined, since it would have a denominator equal to 0. The value of tan (0) is 0, so the cotangent of (0) must be undefined.
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'.
How do you find cot 180?
The value of cot 180 degrees is undefined....Using trigonometry formula, the value of cot 180° can be given in terms of other trigonometric functions as:cos(180°)/sin(180°)± cos 180°/√(1 - cos²(180°))± √(1 - sin²(180°))/sin 180°± 1/√(sec²(180°) - 1)± √(cosec²(180°) - 1)1/tan 180°
What is the cot of 270?
0What is the Value of Cot 270 Degrees? The value of cot 270 degrees is 0. Cot 270 degrees can also be expressed using the equivalent of the given angle (270 degrees) in radians (4.71238 . . .) ⇒ 270 degrees = 270° × (π/180°) rad = 3π/2 or 4.7123 . . .
What is the cot of 90 degrees?
zeroTherefore, the value of Cot 90 degrees is equal to zero.
The Unit Circle Flashcards | Quizlet
The side opposite a 30° angle is the same as the side adjacent to a 60° angle in a right triangle. On a unit circle, the y (sin) distance of a 30° angle is the same as the x (cos) distance of a 60° angle.

What is Cotangent Formula?
For a given right triangle ABC as shown below, where A is an acute angle,
Solved Examples using Cotangent Formula
If the side lengths of a right-angled triangle ABC is 13 units, 12 units, and 5 units, find the value of cot A.
When are trigonometric functions undefined?
Trigonometric functions are undefined when they represent fractions with denominators equal to zero. Secant is the reciprocal of cosine, so the secant of any angle x for which cos x = 0 must be undefined, since it would have a denominator equal to 0.
What is the angle of a trigonometric function?
Possible Answers: Correct answer: Explanation: Trigonometric functions are equal to 0, 1, -1 or undefined when the angle lies on an axis, meaning that the angle is equal to 0, 90, 180 or 270 degrees (0, (pi)/2, pi or 3 (pi)/2 in radians.)
Is a cotangent a tangent?
Cotangent is the reciprocal of tangent, so the cotangent of any angle x for which tan x = 0 must be undefined, since it would have a denominator equal to 0. The value of tan (0) is 0, so the cotangent of (0) must be undefined. Report an Error.
Is secant a reciprocal?
Secant is the reciprocal of cosine, so the secant of any angle x for which cos x = 0 must be undefined, since it would have a denominator equal to 0. The value of cos (pi/2) is 0, so the secant of (pi)/2 must be undefined. Report an Error.
What is a unit circle?
The unit circle is another way to work with trigonometric functions. Instead of degrees, the unit circle is shown using radians, as you can see in the image below. Unit Circle. This unit circle shows both the degrees and radians. We can come up with these exact same answers using the unit circle.
How to find the cotangent of a 45 degree angle?
To find the cotangent of the 45-degree angle, it is adjacent/opposite, or 1/1, or 1. Using the 30-60-90 triangle, the cotangent of the 30-degree angle is sqrt (3)/1, or square root of 3. The cotangent of the 60-degree angle is 1/sqrt (3).
What is the reciprocal function of a tangent?
This is the reciprocal function of the tangent function. The tangent function is sine/cosine, so the cotangent function is cosine/sine. When using the 45-45-90 triangle or the 30-60-90 triangle, the cotangent can be found by adjacent/opposite.
How to use cotangent?
Cotangent is used the same way the sine, cosine, and tangent functions are used. You can use them based on a right triangle, using the opposite and adjacent sides of the triangle, or you can use it based on the unit circle, which shows the angles in radians.
What is trigonometric function?
The application of trigonometric (trig) functions is widely used in our world. These functions are one of the basic math functions in areas like triangulation, which is used in criminal investigations and cell service. They're also used in navigation, surveying, computer graphics, and music theory. Did you know the shape ...
What are the two functions of a trigonometric function?
Let's take a few moments to review the important information that we learned. All trigonometric functions and identities are based on two functions, sine and cosine. The cotangent function is one of six basic functions in trigonometry. This is the reciprocal function of the tangent function.
What is the cotangent of a unit circle?
The cotangent as a line segment of the unit circle. Like the other trigonometric functions, the cotangent can be represented as a line segment associated with the unit circle. The diagram shows the cotangent for an angle of rotation θ of forty-five degrees (measured anti-clockwise from the positive x -axis).
Why is the cotangent value undefined?
Because the cotangent function is the reciprocal of the tangent function, the cotangent value will be undefined when the tangent value is zero, and zero when the tangent value is undefined.
What is a reciprocal function?
A reciprocal function is one that is the reciprocal (or multiplicative inverse) of another function (see below). The cotangent function (usually abbreviated as cot) is the reciprocal function of the tangent function. As with the other trigonometric functions in modern use, the cotangent function was certainly known to Arab scholars, ...
What is the period of a cotangent function?
Like the tangent function, the period of the cotangent function is one hundred and eighty degrees ( 180° ), or π.
Can you find the angle of a trigonometric function?
Finding the angle is not quite as straightforward as for the three main trigonometric functions, as most calculators do not have a dedicated button for the arccotangent function (which is the inverse of the cotangent function). Fortunately, there is a relatively simple way around that.
