STD 3 to 5 na balkone Bhagakar Shikhavo Saraltathi
In India, mathematics and astronomy always went together in the ancient past. Many new discoveries in mathematics had their origins in astronomical problems. Aryabhateeya (499 CE) of Aryabhata is the first discovered text on mathematical astronomy in India and has four chapters, one of which is completely devoted to mathematics. It has results in arithmetic, algebra, geometry and trigonometry. Trigonometry in its modern form has its origins in India. For computations, the Indian jyaa is far more convenient than the Greek chord (Pictures 1 and 2). Actually, the word ‘sine’ is linked to jyaa; jeevaa is another word for jyaa. This was read as jayb in Arabic that means ‘pocket’ or ‘fold’, which was translated into Latin as ‘sinus’. This later became ‘sine', which we now use.
