Simplify cos(1/2)

Problem

cos(1/2)

Solution

1. Identify the expression as the cosine of a constant value, where the argument 1/2 is measured in radians.

2. Determine if the value corresponds to a standard angle on the unit circle. Since 1/2 radians (approximately 28.65 is not a standard angle like π/6 π/4 or π/3 the expression cannot be simplified into a simpler exact radical form.

3. Conclude that the expression is already in its simplest exact form.

Final Answer

cos(1/2)=cos(1/2)
