Find the Exact Value sin(-10)

Problem

sin(−10)

Solution

1. Identify the angle and the trigonometric function. The task asks for the exact value of sin(−10)

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

3. Rewrite the expression using this identity.

sin(−10)=−sin(10)

4. Determine if the angle 10 is a standard reference angle (like 30 45 or 60. Since 10 is not a standard angle, its exact value cannot be expressed using simple radicals or integers.

5. Conclude that the simplest exact form is the expression itself or its identity equivalent.

Final Answer

sin(−10)=−sin(10)
