Answer

Final Answer: The value of the expression $\cos^{- 1} \frac{1}{4}$ rounded to two decimal places is $1.32$ radians.

Steps

Step 1 ：The question is asking for the inverse cosine of 1/4, rounded to two decimal places. The inverse cosine function, also known as arccos, is the inverse function of cosine. It returns the angle whose cosine is a given number.

Step 2 ：Calculate the inverse cosine of 1/4.

Step 3 ：The result will be in radians, as required by the question.

Step 4 ：The value of the expression $\cos^{- 1} \frac{1}{4}$ is approximately 1.32.

Step 5 ：Final Answer: The value of the expression $\cos^{- 1} \frac{1}{4}$ rounded to two decimal places is $1.32$ radians.
