Problem

sin(25)

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 25 is not a standard reference angle, the expression cannot be simplified further into a basic radical or integer form without using a calculator for a decimal approximation.

Final Answer

sin(25)=sin(25)
