Find the Exact Value cos(24/25)

Problem

cos(24/25)

Solution

1. Identify the expression as the cosine of a value given in radians.

2. Determine if the value 24/25 corresponds to a standard angle on the unit circle (such as 0 π/6 π/4 π/3 or π/2.

3. Conclude that since 24/25 is not a standard angle and no further trigonometric identities or inverse functions are provided to simplify the expression, the exact value is simply the expression itself.

Final Answer

cos(24/25)=cos(24/25)
