What is sin 30?

The sine of 30 degrees (sin 30°) is a trigonometric function that represents the ratio of the length of the side opposite to the angle 30 degrees in a right triangle to the length of the hypotenuse. It can also be expressed as the ratio of the y-coordinate of a point on the unit circle that corresponds to the angle 30 degrees to the radius of the circle.

In numerical terms, sin 30° is equal to 0.5, or 1/2. This means that the side opposite the 30-degree angle is half the length of the hypotenuse in a right triangle with the given angle.

Sin 30° is a common value and frequently used in various fields such as mathematics, physics, engineering, and computer science. It is often used to calculate and analyze various problems involving triangles, angles, and oscillatory motion.
