Mathematics in Ancient and Medieval India c4.s3.11

c4.s3.11

Whatever be the causes of the revival, their effect on the scope of the science of the *gaṇita* in this period was great. Astronomy, which had been a branch of Mathematics, separated out and began to be regarded by the name *jyotiṣa*. Geometry which belonged to a separate group of sciences viz. the *Kalpasūtra*, came to be regarded as an integral part of the *gaṇita*. Thus the readjusted science of the *gaṇita* consisted mainly of arithmetic, algebra and geometry⁵. Trigonometry was probably discovered by that time and came within the scope of *jyotiṣa*. Amongst the Jainas and the Buddhists the *gaṇita* was known by the name *saṃkhyāna* (or science of numbers).
