Solution
Solution Steps
To solve this problem, we need to calculate the inverse cosine (arccos) of the fraction \( \frac{11}{13} \) and then round the result to two decimal places. This involves using a calculator or a programming language like Python to compute the arccosine and format the output.
Step 1: Calculate the Inverse Cosine
To find the value of \( \cos^{-1} \left( \frac{11}{13} \right) \), we use the inverse cosine function. The result is approximately \( 0.5621 \) radians.
Step 2: Round the Result
Round the result from Step 1 to two decimal places. This gives us \( 0.56 \).
Final Answer
The value of the expression is \( \boxed{0.56} \) radians.
