In mathematics, the inverse trigonometric functions (occasionally also called antitrigonometric, [1] cyclometric, [2] or arcus functions [3]) are the inverse functions of the trigonometric functions, under suitably restricted domains. Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, [4 ...
In other words, the domain of the inverse function is the range of the original function, and vice versa, as summarized in Figure 6.3.1. Figure 6.3.1. For example, if f(x) = sin x, then we would write f − 1(x) = sin − 1x. Be aware that sin − 1x does not mean 1 sin x. The following examples illustrate the inverse trigonometric functions:

Inverse trigonometric functions are also called “arc functions” since, for a given value of trigonometric functions, they produce the length of arc needed to obtain that particular value. The inverse trigonometric functions perform the opposite operation of the trigonometric functions such as sine, cosine, tangent, cosecant, secant and cotangent. W...
There are particularly six inverse trig functions for each trigonometry ratio. The inverse of six important trigonometric functions are 1. Arcsine 2. Arccosine 3. Arctangent 4. Arccotangent 5. Arcsecant 6. Arccosecant Let us discuss all six important types of inverse trigonometric functions, along with its definition, formulas, graphs, properties a...

The inverse trigonometric functions are also known as arc functions. Inverse trigonometric functions are defined in a certain interval (under restricted domains). Read more on inverse trigonometric properties here. Trigonometry Basics Trigonometry basics include the basic trigonometry and trigonometric ratios, such as sin x, cos x, tan x, cosec x, ...
The other trigonometric functions also are not one-to-one and thus do not have inverse functions. However, in each case we obtain a one-to-one function by restricting the domain to a suitable interval, either \([-\pi / 2, \pi / 2]\) or \([0, \pi]\). The resulting inverse functions are called the arccosine, arctangent, etc.
Quick Answer: For a right-angled triangle: The sine function sin takes angle θ and gives the ratio opposite hypotenuse. The inverse sine function sin-1 takes the ratio opposite hypotenuse and gives angle θ. And cosine and tangent follow a similar idea. Example (lengths are only to one decimal place): sin (35°) = Opposite / Hypotenuse. = 2.8/4.9.
The inverse trigonometric functions of inverse sine, inverse cosine, or inverse tangent can be found from the basic trigonometric ratios. For example, if sin θ = x then θ = sin −1 x. In the same way, we can find the other inverse trig functions. What is the Use of Inverse Trigonometric Formulas in Inverse Trigonometry?

Understanding and Using the Inverse Sine, Cosine, and Tangent Functions. In order to use inverse trigonometric functions, we need to understand that an inverse trigonometric function “undoes” what the original trigonometric function “does,” as is the case with any other function and its inverse.
