Find the Exact Value sin(12/13)

Problem

sin(12/13)

Solution

1. Identify the expression as the sine of a constant value given in radians.

2. Determine if the value 12/13 corresponds to a standard angle on the unit circle (such as 0 π/6 π/4 π/3 or π/2.

3. Conclude that since 12/13 is not a standard angle and no further context (such as an inverse trigonometric function) is provided, the exact value is simply the expression itself.

Final Answer

sin(12/13)=sin(12/13)
