Step 1: Recall the definition of the secant function and the inverse cosine function.
The inverse cosine function, often denoted as $$cos^{-1}$$ or $$arccos$$, returns the angle whose cosine is a given value.
Step 2: Substitute the inverse cosine of x/ 6 for the argument of the secant function.
Final Answer
