astronomy and astrology. It was Aryabhatta‚ who gave a new direction to trigonometry. The decimal system too was an innovation of India. By the third century B.C. mathematics‚ astronomy and medicine began to develop separately. In the field of mathematics ancient Indians made three distinct contributions‚ the notation system‚ the decimal system and the use of zero. The earliest epigraphic evidence of the use of decimal system belongs to the fifth century A.D. Before these numerals appeared in the West
