How to Use the Calculator

To use the Arccos Calculator, simply input a numeric value between -1 and 1 in the designated field. Upon clicking the ‘Calculate Arccos’ button, the calculator will display the arccosine of the input value in both degrees and radians. Additionally, it provides the calculation process for educational purposes. If you need to start over, use the ‘Clear’ button to reset all fields.

Understanding the Formula and Calculations

The calculator uses the mathematical arccosine function to convert the input value into an angle. The formula for the arccosine in radians is acos(value), and it is converted to degrees using the relation degrees = radians * (180 / π). The output includes the standard arccosine value and, for completeness, its supplementary angle, calculated as 360° - arccosine in degrees and 2π - arccosine in radians.
