Graphs of the Tangent, Cotangent, Cosecant and Secant Functions

Secant, Cosecant, and Cotangent

Secant

The secant of an angle is the reciprocal of its cosine.

$\sec x={\frac {1}{\cos x}}$

Cosecant

The cosecant of an angle is the reciprocal of its sine.

$\operatorname {cosec} x={\frac {1}{\sin x}}$

Cotangent

The cotangent of an angle is the reciprocal of its tangent.

$\cot x={\frac {1}{\tan x}}$
