Find the Exact Value sin(-60 degrees )

Problem

sin(−60)

Solution

1. Apply the odd function identity for the sine function, which states that sin(−θ)=−sin(θ)

sin(−60)=−sin(60)

2. Identify the exact value of sin(60) using the unit circle or a special 30−60−90 right triangle.

sin(60)=√(,3)/2

3. Substitute the value back into the expression to find the final result.

−sin(60)=−√(,3)/2

Final Answer

sin(−60)=−√(,3)/2
