The calculator will find the inverse cosine of the given value in radians and degrees. The inverse cosine $$$ y=\cos^{-1}(x) $$$ or $$$ y=\operatorname{acos}(x) $$$ or $$$ y=\operatorname{arccos}(x) $$$ is such a function that $$$ \cos(y)=x $$$ .

Free Online Inverse Cosine Calculator works in degrees or radians, plus draws triangle.

Inverse cosine is used to determine the measure of angle using the value of the trigonometric ratio cos x. In this article, we will understand the formulas of the inverse cosine function, its domain and range, and hence, its graph. We will also determine the derivative and integral of cos inverse x to understand its properties better.

Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, [4] and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.
