1. Introduction to Cos inverse calculator: -

In trigonometry, the inverse cosine function is crucial for determining the angle associated with a given cosine value. Whether you're a student exploring the intricacies of trigonometric functions or someone curious about real-world applications, this guide will shed light on finding the inverse cosine of a value. Join us as we delve into definitions, formulas, domain and range, solved examples, and practical insights into the inverse cosine function.
$\bold{Definition}$
The inverse cosine function, often denoted as Cos$^{-1}$ arccos, provides the angle whose cosine is a given value. For a given value x, the inverse cosine is defined as: Cos$^{-1}(x) = \theta$ ​

2. What is the Formulae used & conditions required?

$\bold{Formula \space Used}$
The formula for finding the inverse cosine of a value involves determining the angle whose cosine equals the given value: Cos$^{-1}(x) = \theta$ where −1 ≤ x ≤ 1
$\bold{Domain \space and \space Range}$
The domain of Cos$^{-1}(x)$ is [-1, 1], representing valid cosine values.
The range of Cos$^{-1}(x)$ is from $[0, \pi]$

$\bold{Table \space of \space values}$
Here's a quick reference for Cosine values:

x	Cos$^{-1}(x)$
1	$0^o$
$\frac{1}{\sqrt{2}}$	$\frac{\pi}{4}$ or $45^o$
$\frac{1}{2}$	$\frac{\pi}{3}$ or $60^o$

3. How do I calculate the Cos inverse for a given value?

Determine the value for which you want to find the angle.
Use the Cos inverse formula: $Cos^{−1}(θ)$ = Angle whose cosine is θ.
Plug the cosine value into the formula and evaluate it to find the angle.
Ensure you use the correct unit, degrees or radians, for the result.
