Simplify sin(31)

Problem

sin(31^∘)

Solution

1. Identify the expression as the sine 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 31^∘ is not a standard reference angle and no further trigonometric identities or context are provided, the expression is already in its simplest exact form.

Final Answer

sin(31^∘)=sin(31^∘)
