cot(17) = 3.2708526224503

↓Steps Explained:↓

Calculate cot(17)

cot is found using Adjacent/Opposite

Determine quadrant:

Since 0 ≤ 17 ≤ 90 degrees
it is in Quadrant I

sin, cos and tan are positive.

Determine angle type:

17 < 90°, so it is acute

Simplify Formula

Cot(θ)  =  1
  Tan(θ)

cot(17)  =  1
  Tan(17)

cot(17)  =  1
  0.30573068108793

cot(17) = 3.2708526224503

Using our unit circle measurements, we look up cot(17)cot(17) = 3.2708526224503

Write cot(17) in terms of tan

Since 17° is less than 90...
We can express this as a cofunction

cot(θ) = tan(90 - θ)

cot(17) = tan(90 - 17)

cot(17) = tan(73)
