MySQL COT() Function
The COT() function in MySQL calculates the cotangent of an angle. The cotangent is the reciprocal of the tangent (cot(x) = 1 / tan(x)). The input to the function is an angle expressed in radians.
COT(): Definition and Usage
The cotangent is a trigonometric function useful in various mathematical and geometrical calculations. COT() provides a convenient way to compute cotangent values directly within your MySQL queries. Note that if the input is 0, the function may return an error or NULL, as the cotangent of 0 is undefined.
