Cotangent Function
Function f of {x ∈ [latex]\mathbb{R}[/latex] | x ≠ kπ where k ∈ [latex]\mathbb{Z}[/latex]} in [latex]\mathbb{R}[/latex] defined f(x) = [latex]\dfrac{1}{\textrm{tan}(x)}[/latex].
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).
