The sine of 30 degrees (sin 30°) can be calculated using the trigonometric values of special angles. In this case, 30 degrees is a special angle because it is one of the angles in a 30-60-90 degree right triangle. In a 30-60-90 triangle, the sides are in the ratio 1:√3:2.

The sine values in degrees oscillate from -1 to +1. The angles between 0° and 90° have positive values starting from 0 and ending at +1. All values of the sine in degrees repeat cyclically. You can calculate them with the following relationships: sin (α + 90°) = sin (90° - α); sin (α + 180°) = -sin (α); and.

A 30-60-90 triangle is a right triangle with angles of 30 degrees, 60 degrees, and 90 degrees. It has special properties related to the lengths of its sides, which can make it very helpful when learning trigonometry. The ratios of the side lengths are constant for all 30-60-90 triangles: the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60.
How do you find the value of sin 60? Socratic
The value of Sin(30) holds significance in the analysis of special triangles like the 30-60-90 triangle and in geometric calculations. This is where Sin(30) comes into play. The value of the sine of the 30-degree angle, mathematically expressed as Sin(30), is equal to 1/2. This means that the short side will be half the length of the hypotenuse.
