What is the sine of 30 degrees?

The sine of 30 degrees, denoted as sin(30°), can be calculated as 0.5.

To understand how this value is obtained, we can use the unit circle. The unit circle is a circle with a radius of 1 unit centered at the origin of a coordinate plane.

To find the sine of an angle, we draw a line from the origin at an angle of 30 degrees, which intersects the unit circle. The y-coordinate of the point where the line intersects the unit circle represents the sine of that angle.

At 30 degrees, the line intersects the unit circle at a point where the y-coordinate is 0.5. This means that sin(30°) is equal to 0.5.

Therefore, sin(30°) = 0.5.
