What Is Inverse Cosine?

The inverse cosine, also known as arccosine (arccos), is the reverse operation of the cosine function in trigonometry. If cos⁡(θ)=x\cos(\theta) = xcos(θ)=x, then arccos⁡(x)=θ\arccos(x) = \thetaarccos(x)=θ. It determines the angle (θ\thetaθ) when the cosine value (xxx) is known.

The inverse cosine function is particularly important in:

• Calculating unknown angles in triangles.
• Applications in physics, engineering, and computer graphics.
• Modeling periodic phenomena like waves.

The range of the inverse cosine function is [0,π][0, \pi][0,π] radians, or 0∘0^\circ0∘ to 180∘180^\circ180∘.
