Trigonometry: Triangles
built 649 days ago
Trigonometry is a branch of mathematics that is used to solve problems involving distances and angles. It has wide applications in navigation, surveying, astronomy and engineering. Trigonometry is ... used in the study of periodic events such as the tides of the ocean. Toolmakers, fitters and many others need to be familiar with trigonometry and be able to calculate an angle or side-length of a triangle.

Trigonometry is a branch of mathematics which deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right angled triangles). Triangles on a sphere are ... studied, in spherical trigonometry. Trigonometry specifically deals with the relationships between the sides and the angles of triangles, that is, the trigonometric functions, and with calculations based on these functions.

Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently, much of science and precalculus.

Trigonometry is a branch of mathematics that solves problems relating to plane and spherical triangles. Its principles are based on the fixed proportions of sides for a particular angle in a right-angled triangle, the simplest of which are known as the sine, cosine, and tangent (so-called trigonometric ratios). Trigonometry is of practical importance in navigation, surveying, and simple harmonic motion in physics.

Trigonometry is the study of angles, triangles, and trigonometric functions such as sine, cosine and tangent. First used by Egyptians and Babylonians, trig has been around for over 3000 years. Trigonometry is used in surveying, navigation, and various sciences such as physics. For an excellent review of Trigonometry, trig subjects and its history, check out Wikipedia.

The word "Trigonometry" is derived from two Greek words meaning measurement or solution of triangles. Trigonometry is a branch of mathematics that deals with the ratio between the sides of a right triangle and its angles. Trigonometry is used in surveying to determine heights and distances, in navigation to determine location and distances, and in fields like nondestructive testing for determining things such as the angle for reflection or refraction of an ultrasound wave.
