The domain of sec inverse x is given by (-∞, -1] U [1, ∞) and its range is [0, π/2) U (π/2, π]. If sec x = y ⇒ x = sec -1 y. Let us see a few examples of how to determine the values of sec inverse x.

Sec 0 = 1/cos 0. Since secant is the inverse of the cosine function, therefore, it is infinity wherever the cosine function is zero. The derivative of a secant function is sec (x) tan (x). According to …
