In the 5th century CE, trigonometry came into our lives. Aryabhata the mathematician introduced trigonometry to the world. I consider him as the father of mathematics. All the advanced concepts that we study in mathematics today have been given to us by Aryabhata. Trigonometry is a branch of mathematics that deals with the relationship between the lengths of sides and the angles of triangle. There six functions of the angle – sine, cosine, tan, cotangent, sec, and cosec. Trigonometry for IIT JEE is easy to learn and easy to score.
