Find the Exact Value sin(47 degrees )

Problem

sin(47)

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. Recognize that 47 is not a standard angle and cannot be expressed as a simple combination (sum or difference) of standard angles using integers.

4. Conclude that the exact value of sin(47) cannot be simplified further into a basic radical form and is typically left as sin(47) or expressed as cos(43) using the cofunction identity.

Final Answer

sin(47)=sin(47)
