Find value of cot 2pi/3

Enter angle in degrees or radians:

Calculate cot(2π/3)

Determine quadrant:

Since our angle is greater than π/2 and less than or equal to lớn π radians, it is located in Quadrant IIIn the second quadrant, the values for sin are positive only.

Determine angle type:

120 is an obtuse angle since it is greater than 90°
Cot(θ)t=1
Tan(θ)
cot(2π/3)=1
Tan(2π/3)
cot(2π/3)=1
-√3
cot(2π/3) = -√3/3
