Trigonometric Functions
The word Trigonometry is derived from the greek words , 'Trigon' and 'Metron' and it means 'Measuring the sides of a triangle'. The subject was originally developed to solve geometric problems involving triangles. It was studied by sea captians for navigation, surveyor to map out the new lands, by engineers and others. Currently Trigonometry isused in many areas such as the Science of seismology , designing electric circuits, describing the state atom, predicting the heights of tides in the ocean, analysing a musical tone and in many other areas.
