# What is the range of the function y = cot x?

Range of $C o t x$ is $\left(- \infty , + \infty\right)$
The cotangent function can take up any values depending on the value of $x$ , the independent variable.
And thus, the range $\left(- \infty , + \infty\right)$ is justified.
The domain is all real numbers other than integral multiples of $\pi$ where, the function is not defined.
