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.
