Find the Exact Value sin(77)

Problem

sin(77)

Solution

1. Identify the expression as the sine of an angle measured in degrees.

2. Determine if the angle 77 is a standard reference angle (like 0,30,45,60,90.

3. Conclude that since 77 is not a standard angle and cannot be easily expressed as a sum or difference of standard angles to produce a simple radical form, the exact value is written in its trigonometric form.

4. Represent the value using the sine function.

Final Answer

sin(77)=sin(77)
