Formula & Methodology
The formula for cotangent is cot(θ) = adj/opp. Our calculator uses this formula to find the cotangent of the given angle.
Real-World Examples
Example 1
If the adjacent side is 5 units and the opposite side is 3 units, the cotangent is 5/3 ≈ 1.67.
Example 2
If the adjacent side is 10 units and the opposite side is 4 units, the cotangent is 10/4 = 2.5.
Example 3
If the adjacent side is 7 units and the opposite side is 24 units, the cotangent is 7/24 ≈ 0.2917.
