Unlock the power of trigonometry with our free Cos Inverse Calculator. This essential tool allows you to quickly find the angle whose cosine is a given value (x), also known as arccos(x) or inverse cosine. Perfect for students, engineers, and anyone working with angles and trigonometric functions.
Formula:
The Cos Inverse function, often written as `cos⁻¹(x)` or `arccos(x)`, determines the angle (θ) whose cosine is `x`.
Formula: `θ = cos⁻¹(x)` or `θ = arccos(x)`
Where:
- `x` is the cosine value (must be between -1 and 1, inclusive).
- `θ` is the angle in radians or degrees.
