QuestionFind the exact value of .
Studdy Solution
STEP 1
Assumptions1. We are working in radians, not degrees. We are familiar with the properties of the inverse cosine function, specifically that the range of is .
3. We know that is a periodic function with period , which means that for any integer .
STEP 2
We need to determine whether falls within the range of the inverse cosine function, which is .
STEP 3
Since is within the range of the inverse cosine function, we can directly apply the inverse cosine function to .
The exact value of the expression is .
