Introduction
Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry. Today it is the foundation of the practical art of surveying.
A diverse number of fields make use of trigonometry, including:
- acoustics, architecture, astronomy , cartography, civil engineering, geophysics, crystallography, electrical engineering, electronics, land surveying and geodesy, mechanical engineering, machining, medical imaging, number theory, oceanography, optics, pharmacology, probability theory, seismology,and visual perception.
