SQL Server COT() Function

The COT() function in SQL Server calculates the cotangent of an angle. The cotangent is the reciprocal of the tangent; mathematically, cot(x) = 1 / tan(x). The input angle is in radians, and the function returns the cotangent as a numeric value.

COT(): Definition and Usage

Cotangent is a trigonometric function frequently used in various mathematical, scientific, and engineering calculations. SQL Server's COT() function provides a direct way to compute cotangent values within your SQL queries.
