cot(86) = 0.06992681366702
↓Steps Explained:↓
Calculate cot(86)
cot is found using Adjacent/Opposite
Determine quadrant:
Since 0 ≤ 86 ≤ 90 degrees
it is in Quadrant I
sin, cos and tan are positive.
Determine angle type:
86 < 90°, so it is acute
Simplify Formula
| Cot(θ) = | 1 |
| Tan(θ) |
| cot(86) = | 1 |
| Tan(86) |
| cot(86) = | 1 |
| 14.300665904239 |
cot(86) = 0.06992681366702
Using our unit circle measurements, we look up cot(86)cot(86) = 0.06992681366702Write cot(86) in terms of tan
Since 86° is less than 90...
We can express this as a cofunction
cot(θ) = tan(90 - θ)
cot(86) = tan(90 - 86)
cot(86) = tan(4)
