between length and angles of triangles.

Trigonometry is the division of mathematics that is concerned with various properties of

trigonometric functions and the applications of those functions to determine the unknown

angles and sides of a triangle. Trigonometry is an important topic of mathematics that

taught to students in their high school mathematics curriculum. Trigonometry is also of

paramount importance in daily life.

We are just mentioning those technological fields where there is an extensive used of

trigonometric concepts.
