Arccot Calculator

Find inverse cotangent angle in degrees and radians

Input Value

Arccot Formula

θ = arccot(x), where cot(θ) = x

Arccot reverses the cotangent function. It takes a cotangent ratio and returns the principal angle that produces that ratio.

Arccot conventions vary. This calculator returns a principal angle from 0° to 180°.

How Arccot Works

Cotangent compares adjacent over opposite. Arccot works backward from that ratio to recover an angle in the selected principal range.

Inverse Cotangent

Arccot reverses cotangent.

Input Range

Any real number is allowed.

Output Range

Principal angle is 0° to 180°.

Ratio Link

cot θ = adjacent/opposite.

💡 Example: arccot(1)=45°=0.785398 rad.
