• angle_in_radians: The angle value expressed in radians.

? What is Cotangent?

? Example Usage

SELECT COT(PI()/4);  -- Result: 1 (cot 45° = 1)SELECT COT(PI()/3);  -- Result: approx 0.577

? Notes

• Input must be in radians, not degrees.

• Convert degrees to radians if needed:

SELECT COT(RADIANS(45));

• Supported in MySQL, SQL Server, Oracle, and PostgreSQL (in PostgreSQL use 1 / TAN(angle) if COT() is not available).

If you want examples for a specific database or help converting degrees to radians, just ask!
