Understand that $ \cos^{-1}(x) $ is the inverse cosine function, which gives the angle whose cosine is $ x $.

Identify the value for which you need to find the inverse cosine: $ x = \frac{1}{4} $.

Use a calculator to find $ \cos^{-1}\left(\frac{1}{4}\right) $. Ensure your calculator is set to radians mode.

Enter $ \frac{1}{4} $ into the calculator and apply the inverse cosine function to find the angle in radians.

Round the result to two decimal places to get the final answer.
