WHAT IS TRIGOMETRY

 

Atul Doshi

Hi Atul Doshi !
Mark as answer and close

The word "Trigonometry" is derived from two Greek words, trigonon, "triangle" + metron, "measure".

Trigonometry is a branch of mathematics that deals with the ratio between the sides of a right triangle and its angles.

Trigonometry is related with planar right-angle triangles (each of which is a two-dimensional triangle with one angle equal to 90 degrees).

Trigonometric concepts are used to minimize the amount of measuring involved.

Trigonometry is used in surveying to determine heights and distances, in navigation to determine location and distances, etc.

There are three principle functions in trigonometry: sine A, cosine A, and tangent A where A is an angle. These are typically abbreviated for use in algebra to: sinA, cosA, and tanA. These terms are defined in terms of a right triangle.
