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 x-axis. 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 x-axis.
- The cosec of 360 degrees equals the reciprocal of the y-coordinate(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/√(1-cos²(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 x-axis, the final value of cosec 360° is undefined.
