What is the definition of the secant function?

Back

The secant function, denoted as \sec x, is defined as the reciprocal of the cosine function: \sec x = \frac{1}{\cos x}.

Front

What is the definition of the cosecant function?

Back

The cosecant function, denoted as \csc x, is defined as the reciprocal of the sine function: \csc x = \frac{1}{\sin x}.

Front

What is the definition of the tangent function?

Back

The tangent function, denoted as \tan x, is defined as the ratio of the sine function to the cosine function: \tan x = \frac{\sin x}{\cos x}.

Front

What is the Quotient Identity in trigonometry?

Back

The Quotient Identity states that \tan x = \frac{\sin x}{\cos x}.
