Understanding Cotangent (cot)

Cotangent Definition:
The cotangent function is one of the six primary trigonometric functions. It is defined as the reciprocal of tangent:
cot(θ) = 1 / tan(θ) = cos(θ) / sin(θ)

Where:
θ is the angle (in degrees or radians).
Cotangent is undefined whenever sin(θ) = 0.
Cotangent is widely used in geometry, trigonometry, engineering, architecture, navigation, and physics to calculate ratios of sides in right triangles and to model periodic functions.

👉 Key Reminder:
If tan(θ) = opposite / adjacent, then
cot(θ) = adjacent / opposite

Formula to Calculate Cotangent

The formula is straightforward:
cot(θ) = cos(θ) / sin(θ)
Or equivalently:
cot(θ) = 1 / tan(θ)
Our Cotangent Calculator makes this process effortless by instantly providing results in both degrees and radians.

Examples of Cotangent Calculations

In Degrees:

cot(30°) = cos(30°)/sin(30°) = (√3/2)/(1/2) = √3 ≈ 1.732 → ✅ So, cot(30°) ≈ 1.732

cot(45°) = cos(45°)/sin(45°) = (√2/2)/(√2/2) = 1 → ✅ So, cot(45°) = 1

cot(60°) = cos(60°)/sin(60°) = (1/2)/(√3/2) = 1/√3 ≈ 0.577 → ✅ So, cot(60°) ≈ 0.577

cot(120°) = cos(120°)/sin(120°) = (−1/2)/(√3/2) = −1/√3 ≈ −0.577 → ✅ So, cot(120°) ≈ −0.577

In Radians (Whole Numbers):

cot(1 rad) = cos(1)/sin(1) ≈ 0.5403/0.8415 ≈ 0.642 → ✅ So, cot(1 rad) ≈ 0.642

cot(2 rad) = cos(2)/sin(2) ≈ −0.4161/0.9093 ≈ −0.457 → ✅ So, cot(2 rad) ≈ −0.457

cot(3 rad) = cos(3)/sin(3) ≈ −0.9900/0.1411 ≈ −7.015 → ✅ So, cot(3 rad) ≈ −7.015

cot(4 rad) = cos(4)/sin(4) ≈ −0.6536/−0.7568 ≈ 0.863 → ✅ So, cot(4 rad) ≈ 0.863

cot(5 rad) = cos(5)/sin(5) ≈ 0.2837/−0.9589 ≈ −0.295 → ✅ So, cot(5 rad) ≈ −0.295
