Cosec 1200 Degrees
The value of cosec 1200 degrees is 1.1547005. . .. Cosec 1200 degrees in radians is written as cosec (1200° × π/180°), i.e., cosec (20π/3) or cosec (20.943951. . .). In this article, we will discuss the methods to find the value of cosec 1200 degrees with examples.
 Cosec 1200°: 2/√3
 Cosec 1200° in decimal: 1.1547005. . .
 Cosec (1200 degrees): 1.1547005. . . or 2/√3
 Cosec 1200° in radians: cosec (20π/3) or cosec (20.9439510 . . .)
What is the Value of Cosec 1200 Degrees?
The value of cosec 1200 degrees in decimal is 1.154700538. . .. Cosec 1200 degrees can also be expressed using the equivalent of the given angle (1200 degrees) in radians (20.94395 . . .).
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 1200 degrees = 1200° × (π/180°) rad = 20π/3 or 20.9439 . . .
∴ cosec 1200° = cosec(20.9439) = 2/√3 or 1.1547005. . .
Explanation:
For cosec 1200°, the angle 1200° > 360°. Given the periodic property of the cosecant function, we can represent it as cosec(1200° mod 360°) = cosec(120°). The angle 1200°, coterminal to angle 120°, is located in the Second Quadrant(Quadrant II).
Since cosecant function is positive in the 2nd quadrant, thus cosec 1200 degrees value = 2/√3 or 1.1547005. . .
Similarly, cosec 1200° can also be written as, cosec 1200 degrees = (1200° + n × 360°), n ∈ Z.
⇒ cosec 1200° = cosec 1560° = cosec 1920°, and so on.
Note: Since, cosecant is an odd function, the value of cosec(1200°) = cosec(1200°).

Using trigonometry formulas, we can represent the cosec 1200 degrees as:
 ± 1/√(1cos²(1200°))
 ± √(1 + tan²(1200°))/tan 1200°
 ± √(1 + cot²(1200°))

Note: Since 1200° lies in the 2nd Quadrant, the final value of cosec 1200° will be positive.
We can use trigonometric identities to represent cosec 1200° as,
 cosec(180°  1200°) = cosec(1020°)
 cosec(180° + 1200°) = cosec 1380°
 sec(90°  1200°) = sec(1110°)
 sec(90° + 1200°) = sec 1290°
Cosec 1200 Degrees Using Unit Circle
To find the value of cosec 1200 degrees using the unit circle, represent 1200° in the form (3 × 360°) + 120° [∵ 1200°>360°] ∵ cosecant is a periodic function, cosec 1200° = cosec 120°.
 Rotate ‘r’ anticlockwise to form 120° or 1200° angle with the positive xaxis.
 The cosec of 1200 degrees equals the reciprocal of the ycoordinate(0.866) of the point of intersection (0.5, 0.866) of unit circle and r.
Hence the value of cosec 1200° = 1/y = 1.1547 (approx)
