Trigonometry Formula

Trigonometry is a branch of mathematics that deals with the study of relationships between the angles and sides of triangles. The fundamental trigonometric functions are sine, cosine, tangent, and cotangent, which are denoted as sin x, cos x, tg x, and ctg x respectively.

The trigonometric functions can be defined in terms of the sides of a right-angled triangle. For a right-angled triangle with an angle x, the trigonometric functions are defined as follows: - sin x = opposite/hypotenuse - cos x = adjacent/hypotenuse - tg x = opposite/adjacent - ctg x = adjacent/opposite

These functions are used to solve for unknown angles or sides in a triangle, and they have various applications in fields such as physics, engineering, and astronomy.
