Trigonometry, the branch of mathematics concerned with specific functions of angles. There are six functions commonly used in trigonometry: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Learn more about trigonometry in this article.
Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [ 1 ] is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
Learn what trigonometry is, how to use sine, cosine and tangent functions, and how to solve triangles. Trigonometry is all about triangles, angles and distances, and is used in science, engineering and more.
Learn trigonometry—right triangles, the unit circle, graphs, identities, and more.
Trigonometry is the branch of mathematics that studies the relationships between the sides and angles of triangles. Learn about trigonometric functions, identities, formulas, and how to apply them to non-right triangles.
Trigonometry concerns the description of angles and their related sides, particularly in triangles. While of great use in both Euclidean and analytic geometry, the domain of the trigonometric functions can also be extended to all real and complex numbers, where they become useful in differential equations and complex analysis.
10 paź 2024 · Trigonometry is the study of angles and angular relationships of planar and three-dimensional figures. Learn the definitions, properties, and identities of the trigonometric functions using the unit circle, complex exponentials, and mnemonics.
