Trigonometry is all about triangles. It studies the relationship between involving lengths and angles of triangle. The basic idea is that every shape can ultimately be converted to a group of triangles and thus their angles and dimensions can be worked out using trigonometric functions such as sine, cosine etc. Applications of trigonometry span across many diversified fields like physics, engineering, astronomy, music and acoustics, biology, ecology etc. It also laid the foundations for surveying.
Did you know that trigonometry was discovered nearly 2500 years ago to undertake astronomical studies! GPS devices use trigonometry to accurately determine your location on earth and also for monitoring, recording and predicting the movement of Earth.
