Cot 300 Degrees
The value of cot 300 degrees is -0.5773502. . .. Cot 300 degrees in radians is written as cot (300° × π/180°), i.e., cot (5π/3) or cot (5.235987. . .). In this article, we will discuss the methods to find the value of cot 300 degrees with examples.
- Cot 300°: -(1/√3)
- Cot 300° in decimal: -0.5773502. . .
- Cot (-300 degrees): 0.5773502. . . or 1/√3
- Cot 300° in radians: cot (5π/3) or cot (5.2359877 . . .)
What is the Value of Cot 300 Degrees?
The value of cot 300 degrees in decimal is -0.577350269. . .. Cot 300 degrees can also be expressed using the equivalent of the given angle (300 degrees) in radians (5.23598 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 300 degrees = 300° × (π/180°) rad = 5π/3 or 5.2359 . . .
∴ cot 300° = cot(5.2359) = -(1/√3) or -0.5773502. . .
Explanation:
For cot 300 degrees, the angle 300° lies between 270° and 360° (Fourth Quadrant). Since cotangent function is negative in the fourth quadrant, thus cot 300° value = -(1/√3) or -0.5773502. . .
Since the cotangent function is a periodic function, we can represent cot 300° as, cot 300 degrees = cot(300° + n × 180°), n ∈ Z.
⇒ cot 300° = cot 480° = cot 660°, and so on.
Note: Since, cotangent is an odd function, the value of cot(-300°) = -cot(300°).

- cos(300°)/sin(300°)
- ± cos 300°/√(1 - cos²(300°))
- ± √(1 - sin²(300°))/sin 300°
- ± 1/√(sec²(300°) - 1)
- ± √(cosec²(300°) - 1)

We can use trigonometric identities to represent cot 300° as,
- tan (90° - 300°) = tan(-210°)
- -tan (90° + 300°) = -tan 390°
- -cot (180° - 300°) = -cot(-120°)
Cot 300 Degrees Using Unit Circle
To find the value of cot 300 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 300° angle with the positive x-axis.
- The cot of 300 degrees equals the x-coordinate(0.5) divided by y-coordinate(-0.866) of the point of intersection (0.5, -0.866) of unit circle and r.
Hence the value of cot 300° = x/y = -0.5774 (approx).
