# Cotangent Function

## Cotangent Function

Function f of {x ∈ $$\mathbb{R}$$  | xkπ where k ∈ $$\mathbb{Z}$$} in $$\mathbb{R}$$ defined f(x) = $$\dfrac{1}{\textrm{tan}(x)}$$.

### Notation

The cotangent function is noted as “cot(x)” and is read as “cotangent of x.”

We sometimes see the notation “cotg(x)” to indicate “cotangent of x.

### Example

Here is the representation of the basic function defined by the relation f (x) = cot(x).
