What is trigonometria?

Trigonometria is a branch of mathematics that deals with the study of relationships involving the lengths and angles of triangles. It is commonly used in various fields such as physics, engineering, astronomy, and geography to calculate distances, angles, and other measurements.

The main trigonometric functions include sine, cosine, tangent, secant, cosecant, and cotangent, which are defined based on the ratios of the sides of a right triangle. These functions can also be defined using the unit circle, where the coordinates of points on the circle correspond to the values of the trigonometric functions for a given angle.

Trigonometry also involves the use of trigonometric identities, formulas, and equations to solve various problems involving triangles and angles. It is a fundamental concept in mathematics and is widely used in calculus, geometry, and other branches of mathematics.

Overall, trigonometria plays a crucial role in various fields and is essential for understanding and solving complex mathematical problems.
