What Is Trigonometry What Is Trigonometry Trigonometry (from Greek trigōnon "triangle" + metron "measure") is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies. It is also the foundation of the practical art of surveying.Trigonometry basics are often taught in school either as a separate course or as part of a precalculus course. The trigonometric functions are pervasive in parts of pure mathematics and applied mathematics such as Fourier analysis and the wave equation, which are in turn essential to many branches of science and technology.

Spherical trigonometry studies triangles on spheres, surfaces of constant positive curvature, in elliptic geometry. It is fundamental to astronomy and navigation. Trigonometry on surfaces of negative curvature is part of Hyperbolic geometry. The inverse functions are called the arcsine, arccosine, and arctangent, respectively. There are arithmetic relations between these functions, which are known as trigonometric identities. The cosine, cotangent, and cosecant are so named because they are respectively the sine, tangent, and secant of the complementary angle abbreviated to "co-". With these functions one can answer virtually all questions about arbitrary triangles by using the law of sines and the law of cosines. These laws can be used to compute the remaining angles and sides of any triangle as soon as two sides and their included angle or two angles and a side or three sides are known. These laws are useful in all branches of geometry, since every polygon may be described as a finite combination of triangles. Trigonometry is a separate branch of mathematics which deals with Triangles, it studies the relationship between their sides and angles by defining the separate trigonometric Functions. The Trigonometric Functions are universally adopted in the part of pure mathematics and applied mathematics. Read More About Area Of Isosceles Trapezoid Calculator

The introduction to Trigonometry is quite simpler, the basis of its function depends upon Right Angle triangle. Hence to make a complete angle two acute angles are added to the 900, these are known as complementary angles. If the length of the one side is given than we can easily determine other two sides of the triangle. Now we will see what is trigonometry. The ratios of trigonometry are given with the help of the following trigonometric functions. If any one angle is known suppose angle ‘C’ than we can find sides of triangle, where x, y, z are considered as the sides of the triangle: There are six trigonometric functions sine, cosine, tangent, secant, cosecant, cotangent.
