Simplify sin(20)

Problem

sin(20)

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 20 is not a standard reference angle, the expression sin(20) is already in its simplest exact radical form.

4. Provide the decimal approximation if required, though the exact form remains sin(20)

Final Answer

sin(20)=sin(20)
