Discover the angle corresponding to a given cosine ratio with our easy-to-use Inverse Cosine Calculator. Find arccos(x) for values between -1 and 1, getting results in degrees. Perfect for solving trigonometry and geometry problems, quickly determine unknown angles.
Formula:
The Inverse Cosine function, denoted as arccos(x) or cos-1(x), determines the angle (θ) whose cosine is x.
Formula: θ = arccos(x)
Where:
xis the cosine ratio (a value between -1 and 1).θis the resulting angle in degrees.
