## Which is the inverse of the arctan ( x ) function?

Online arctan (x) calculator. Inverse tangent calculator. The arctangent function is the inverse function of y = tan (x). arctan ( y) = tan -1 ( y) = x + kπ

## How to evaluate the composition of arctan and Tan?

These properties allow us to evaluate the composition of trigonometric functions. If x is within the domain, evaluating a composition of arctan and tan is relatively simple. We can also make compositions using all the other trigonometric functions: sine, cosine, cosecant, secant, and cotangent.

## How to find the secant of arctan ( )?

Given arctan () = θ, we can find that tan (θ) = . The right triangle below shows θ and the ratio of its opposite side to its adjacent side. To find secant, we need to find the hypotenuse since sec (θ)=. Let c be the length of the hypotenuse. Using the Pythagorean theorem,
