Question Video Using Trigonometric Values of Special Angles to Evaluate Trigonometric
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.

Trigonometry. Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest.

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.
