What is the definition of the tangent function?

Back

The tangent function, denoted as tan(x), is the ratio of the opposite side to the adjacent side in a right triangle. It can also be defined as tan(x) = sin(x)/cos(x).

What is the range of the inverse tangent function, tan^-1(x)?

Back

The range of the inverse tangent function, tan^-1(x), is (-π/2, π/2).

What is the relationship between sec^-1(x) and cos(x)?

Back

sec^-1(x) is the angle whose secant is x, which means cos(sec^-1(x)) = 1/x.

Front

What is the definition of the cosecant function?

Back

The cosecant function, denoted as csc(x), is the reciprocal of the sine function: csc(x) = 1/sin(x).

Front

What is the domain of the secant function?

Back

The domain of the secant function, sec(x), is all real numbers except for x = (2n+1)π/2, where n is an integer.
