Answer 2

The sine function is periodic, with a period of 360 degrees (or 2π radians). It has symmetries around the origin, which means sin(-x) = -sin(x).

So, to find the value of sin(-30°), you can use the symmetry property:

sin(-30°) = -sin(30°)

Now, the sine of 30 degrees can be calculated. The exact value of sin(30°) is 1/2 or approximately 0.5.

Therefore:

sin(-30°) = -sin(30°) = -0.5

So, sin(-30°) is equal to -0.5.
