What is cot120?

The value of cot 120 degrees is -0.5773502. . .. Cot 120 degrees in radians is written as cot (120° × π/180°), i.e., cot (2π/3) or cot (2.094395. . .). In this article, we will discuss the methods to find the value of cot 120 degrees with examples. Cot 120°: -(1/√3)

What is cot degree?

A cotangent of an angle α is also equal to the ratio between its cosine and sine, so cotα = cosα / sinα. Following from the definition, the function results in an undefined value at certain angles, like 0°, 180°, 360°, and so on.

How do you find the reference angle of tan 150?

The easiest way to find the value of is to first convert the measure of the angle from radians to degrees as, Looking at a graph, a 150° angle lies in quadrant II, therefore the reference angle is θ’ = 180° – 150° = 30°.

What is tan30 value?

In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. The exact value of tan 30° is 0.57735. Tan 30° = 1/√3 = 0.57735.

How do you evaluate COS 150?

Answer: The exact value of cos (150∘) is −√3/2 and sin (150∘) is 1/2.

How do you find the exact value of tan 120?

Tan 120 degrees is the value of tangent trigonometric function for an angle equal to 120 degrees. The value of tan 120° is -√3 or -1.7321 (approx).

Why is cos150?

Now 150 degrees is in the northwest quadrant of the circle, and -150 degrees is in the southwest quadrant. Each of the lines at these two angles is the same left-right distance from the origin, so cos(150) = cos(-150).
