COT

Description

Returns the cotangent of the angle in radians sent through parameters (COT in Transact-SQL).

The cosine is defined as: $cot(x) = \frac{cos(x)}{sin(x)}$ or $cot(x) = \frac{1}{tan(x)}$ To calculate the cosine, the parameter must comply with the constraints of sine and cosine functions.
