The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides) and ‘metron’ (meaning measure). In fact, trigonometry is the study of relationships between the sides and angles of a triangle.
India is the land that gave the world great mathematical concepts such as the decimal system, binary numbers, the concept of zero and so many more. It is also the land that gave birth to great mathematicians such as Aryabhata, Bhaskaracharya and Brahmagupta. While most Indians know about these ancient mathematicians, it is truly surprising that very few Indians are familiar with one of the greatest mathematicians of the twentieth century, born in our own India- the incandescent genius Srinivasa Ramanujan.
