1 / tan(angle * pi / 180)Questions fréquentes
What is cotangent?
Cotangent is the reciprocal of tangent: cot(x) = 1/tan(x).
Why is cotangent undefined at 0° and 180°?
Because tangent is zero at those angles, so the reciprocal is undefined.
Can I input angles in radians?
This calculator uses degrees. For radians, multiply by 180/π.

Conseils et erreurs courantes
Tips
- Remember cot(θ) = cos(θ)/sin(θ).
- Use a calculator with degree mode for quick checks.
- Cotangent is periodic with period 180°.
- For angles where tan is zero, cot is undefined.
Common Mistakes to Avoid
- Forgetting to convert degrees to radians in manual calculations.
- Confusing cotangent with arctangent.
- Using the calculator in radian mode when entering degrees.
Hypothèses et limites
