- Cot 3100° in decimal: 1.1917535. . .
- Cot (-3100 degrees): -1.1917535. . .
- Cot 3100° in radians: cot (155π/9) or cot (54.1052068 . . .)
What is the Value of Cot 3100 Degrees?
The value of cot 3100 degrees in decimal is 1.191753592. . .. Cot 3100 degrees can also be expressed using the equivalent of the given angle (3100 degrees) in radians (54.10520 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 3100 degrees = 3100° × (π/180°) rad = 155π/9 or 54.1052 . . .
∴ cot 3100° = cot(54.1052) = 1.1917535. . .
Explanation:
For cot 3100°, the angle 3100° > 360°. We can represent cot 3100° as, cot(3100° mod 360°) = cot(220°). The angle 3100°, coterminal to angle 220°, is located in the Third Quadrant(Quadrant III).
Since cotangent function is positive in the 3rd quadrant, thus cot 3100 degrees value = 1.1917535. . .
Similarly, given the periodic property of cot 3100°, it can also be written as, cot 3100 degrees = (3100° + n × 180°), n ∈ Z.
⇒ cot 3100° = cot 3280° = cot 3460°, and so on.
Note: Since, cotangent is an odd function, the value of cot(-3100°) = -cot(3100°).
Methods to Find Value of Cot 3100 Degrees

- -tan (90° + 3100°) = -tan 3190°
- -cot (180° - 3100°) = -cot(-2920°)
Cot 3100 Degrees Using Unit Circle
To find the value of cot 3100 degrees using the unit circle, represent 3100° in the form (8 × 360°) + 220° [∵ 3100°>360°] ∵ The angle 3100° is coterminal to 220° angle and also cotangent is a periodic function, cot 3100° = cot 220°.
- Rotate ‘r’ anticlockwise to form 220° or 3100° angle with the positive x-axis.
- The cot of 3100 degrees equals the x-coordinate(-0.766) divided by y-coordinate(-0.6428) of the point of intersection (-0.766, -0.6428) of unit circle and r.
Hence the value of cot 3100° = x/y = 1.1918 (approx).

Example 1: Find the value of (cos (3100°) cosec (1550°) sec (1550°))/2. [Hint: Use cot 3100° = 1.1918]
Solution:
Using trigonometry formulas,
(cos (3100°) cosec (1550°) sec (1550°))/2 = cos (3100°)/(2 sin (1550°) cos (1550°))
Using sin 2a formula,
