Cot 570 Degrees
The value of cot 570 degrees is 1.7320508. . .. Cot 570 degrees in radians is written as cot (570° × π/180°), i.e., cot (19π/6) or cot (9.948376. . .). In this article, we will discuss the methods to find the value of cot 570 degrees with examples.
 Cot 570°: √3
 Cot 570° in decimal: 1.7320508. . .
 Cot (570 degrees): 1.7320508. . . or √3
 Cot 570° in radians: cot (19π/6) or cot (9.9483767 . . .)
What is the Value of Cot 570 Degrees?
The value of cot 570 degrees in decimal is 1.732050807. . .. Cot 570 degrees can also be expressed using the equivalent of the given angle (570 degrees) in radians (9.94837 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 570 degrees = 570° × (π/180°) rad = 19π/6 or 9.9483 . . .
∴ cot 570° = cot(9.9483) = √3 or 1.7320508. . .
Explanation:
For cot 570°, the angle 570° > 360°. We can represent cot 570° as, cot(570° mod 360°) = cot(210°). The angle 570°, coterminal to angle 210°, is located in the Third Quadrant(Quadrant III).
Since cotangent function is positive in the 3rd quadrant, thus cot 570 degrees value = √3 or 1.7320508. . .
Similarly, given the periodic property of cot 570°, it can also be written as, cot 570 degrees = (570° + n × 180°), n ∈ Z.
⇒ cot 570° = cot 750° = cot 930°, and so on.
Note: Since, cotangent is an odd function, the value of cot(570°) = cot(570°).
Methods to Find Value of Cot 570 Degrees
The cotangent function is positive in the 3rd quadrant. The value of cot 570° is given as 1.73205. . . We can find the value of cot 570 degrees by:
 Using Unit Circle
 Using Trigonometric Functions
Cot 570 Degrees Using Unit Circle
To find the value of cot 570 degrees using the unit circle, represent 570° in the form (1 × 360°) + 210° [∵ 570°>360°] ∵ The angle 570° is coterminal to 210° angle and also cotangent is a periodic function, cot 570° = cot 210°.
 Rotate ‘r’ anticlockwise to form 210° or 570° angle with the positive xaxis.
 The cot of 570 degrees equals the xcoordinate(0.866) divided by ycoordinate(0.5) of the point of intersection (0.866, 0.5) of unit circle and r.
Hence the value of cot 570° = x/y = 1.7321 (approx).
Cot 570° in Terms of Trigonometric Functions
Using trigonometry formulas, we can represent the cot 570 degrees as:
 cos(570°)/sin(570°)
 ± cos 570°/√(1  cos²(570°))
 ± √(1  sin²(570°))/sin 570°
 ± 1/√(sec²(570°)  1)
 ± √(cosec²(570°)  1)
 1/tan 570°
Note: Since 570° lies in the 3rd Quadrant, the final value of cot 570° will be positive.
We can use trigonometric identities to represent cot 570° as,
 tan (90°  570°) = tan(480°)
 tan (90° + 570°) = tan 660°

Examples Using Cot 570 Degrees

Example 1: Find the value of 2 cot(570°)/6 cot(390°).
Solution:
Using trigonometric identities, we know, cot(570°) = cot(180°  570°) = cot(390°).
⇒ cot(570°) = cot(390°)
⇒ Value of 2 cot(570°)/6 cot(390°) = 2/6 = 1/3 
Example 2: Find the value of cot 570° if tan 570° is 0.5773.
Solution:
Since, cot 570° = 1/tan 570°
⇒ cot 570° = 1/0.5773 = 1.7321 
Example 3: Find the value of (cos (570°) cosec (285°) sec (285°))/2. [Hint: Use cot 570° = 1.7321]
Solution:
Using trigonometry formulas,
(cos (570°) cosec (285°) sec (285°))/2 = cos (570°)/(2 sin (285°) cos (285°))
Using sin 2a formula,
2 sin (285°) cos (285°) = sin (2 × 285°) = sin 570°
⇒ cos (570°) / sin (570°) = cot 570°
⇒ (cos (570°) cosec (285°) sec (285°))/2 = 1.7321
