Trigonometry

Definition: Trigonometry, informally called trig, is a branch of mathematics that deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right angled triangles). It specifically deals with the relationships between the sides and the angles of triangles; the trigonometric functions, and calculations based upon them. The insights of trigonometry permeate other branches of geometry, such as the study of spheres using spherical trigonometry. Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently remains applicable in natural sciences. Trigonometry is usually taught in secondary schools, often in a precalculus course.

Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. عيد الفطر 2015 صور عيد الفطر مسجات عيد الفطر رسائل عيد الفطر عيد الفطر 2015 صور عيد الفطر مسجات عيد الفطر رسائل عيد الفطر عيد الفطر 2015 صور عيد الفطر مسجات عيد الفطر رسائل عيد الفطر
