Question

2 sin{13π\6}=?

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the value of 2sin(13π/6), we need to know that the sine of an angle is equal to the y-coordinate of a point on the unit circle corresponding to that angle.

In the unit circle, the angle 13π/6 corresponds to (cos(13π/6), sin(13π/6)). To find the y-coordinate, we look at the sin value.

The value of sin(13π/6) is -1/2. Therefore, 2sin(13π/6) is equal to 2 * (-1/2) which equals -1.

So, 2sin(13π/6) = -1.
