Cosec 360 Degrees
The value of cosec 360 degrees is undefined(∞). Cosec 360 degrees in radians is written as cosec (360° × π/180°), i.e., cosec (2π) or cosec (6.283185. . .). In this article, we will discuss the methods to find the value of cosec 360 degrees with examples.
 Cosec 360°: undefined(∞)
 Cosec (360 degrees): undefined
 Cosec 360° in radians: cosec (2π) or cosec (6.2831853 . . .)
What is the Value of Cosec 360 Degrees?
The value of cosec 360 degrees is undefined(∞). Cosec 360 degrees can also be expressed using the equivalent of the given angle (360 degrees) in radians (6.28318 . . .).
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 360 degrees = 360° × (π/180°) rad = 2π or 6.2831 . . .
∴ cosec 360° = cosec(6.2831) = undefined(∞)
Explanation:
For cosec 360 degrees, the angle 360° lies on the positive xaxis. Thus, cosec 360° value = undefined(∞)
Since the cosecant function is a periodic function, we can represent cosec 360° as, cosec 360 degrees = cosec(360° + n × 360°), n ∈ Z.
⇒ cosec 360° = cosec 720° = cosec 1080°, and so on.
Note: Since, cosecant is an odd function, the value of cosec(360°) = cosec(360°) = undefined.
Methods to Find Value of Cosec 360 Degrees
The value of cosec 360° is given as undefined(∞). We can find the value of cosec 360 degrees by:
 Using Unit Circle
 Using Trigonometric Functions
Cosec 360 Degrees Using Unit Circle
To find the value of cosec 360 degrees using the unit circle:
 Rotate ‘r’ anticlockwise to form 0° or 360° angle with the positive xaxis.
 The cosec of 360 degrees equals the reciprocal of the ycoordinate(0) of the point of intersection (1, 0) of unit circle and r.
Hence the value of cosec 360° = 1/y = undefined
Cosec 360° in Terms of Trigonometric Functions
Using trigonometry formulas, we can represent the cosec 360 degrees as:
 ± 1/√(1cos²(360°))
 ± √(1 + tan²(360°))/tan 360°
 ± √(1 + cot²(360°))
 ± sec 360°/√(sec²(360°)  1)
 1/sin 360°
We can use trigonometric identities to represent cosec 360° as,
 cosec(180°  360°) = cosec(180°)
 cosec(180° + 360°) = cosec 540°
 sec(90°  360°) = sec(270°)
 sec(90° + 360°) = sec 450°
Note: Since 360° lies on the positive xaxis, the final value of cosec 360° is undefined.
