# How do you find the value of sin 300º?

The function sin 300º can be written as sin (360º - 60º). By applying the trigonometric identity sin (A - B), we can find the value of sin 300º.

## Answer: The value of sin 300º is - √ 3/2.

Here's the solution.

**Explanation:**

⇒ sin (360º - 60º)

⇒ sin 360º × cos 60º − cos 360º × sin 60º

By substituting the values of sin 360º, sin 60º, cos 360º, and cos 60º, we get

⇒ 0 × 1 /2 - 1 × √ 3/2

⇒ -√ 3/2

### Thus, the value of sin 300º is -√ 3/2.
