Trigonometry, at it's most basic level, is concerned with the measurement of triangles - calculations of unknown lengths and angles the trigometric functions have a number of practical applications in real life and also help in the solutions of problems in many branches of mathematics. Trigonometry : introduction to trigonometry,types of triangles,right angled triangle, definition and some examples -ipracticemath. Trigonometry is a branch of mathematics concerned with the lengths of the sides and size of the angles of triangles because many physical questions can be framed in terms of triangles, trigonometry has found wide use in the physical sciences and engineering. A brief introduction to rational trigonometry greek approach to measurement n j wildberger euclid does not deal directly with distancethe ancient greeks understood the meaning of saying two segments in the same direction were in the ratio `three to two', but they did not have a direct notion of distance, because that would have entailed an.
Trigonometry, as the name might suggest, is all about triangles more specifically, trigonometry is about right-angled triangles, where one of the internal angles is 90° trigonometry is a system that helps us to work out missing sides or angles in a triangle. Usually covered in trigonometry, but should be these include such topics as the pythagorean theorem (lecture 2), proof by contradiction (lecture 16), limits (lecture 18) and proof by induction (lecture 23) as well as giving a geometric basis for many of the relationships of trigonometry.
