Problem

cos(5)

Solution

1. Identify the input of the function. The expression cos(5) represents the cosine of 5 radians.

2. Determine if the value corresponds to a common reference angle. The number 5 is not a standard multiple of π (such as π/6 π/4 π/3 or π/2.

3. Evaluate the possibility of simplification. Since 5 is not a special angle and there are no further operations or identities to apply, the exact value is expressed simply as the function itself.

Final Answer

cos(5)=cos(5)
