Simplify cos(52)

Problem

cos(52^∘)

Solution

1. Identify the expression as the cosine of an angle measured in degrees.

2. Determine if the angle is a standard reference angle (such as 0^∘ 30^∘ 45^∘ 60^∘ or 90^∘.

3. Conclude that since 52^∘ is not a standard reference angle, the expression cannot be simplified into a simpler exact radical form without using complex trigonometric identities or approximations.

4. State the expression in its simplest exact form.

Final Answer

cos(52^∘)=cos(52^∘)
