For this, the circumference of each quarter of a circle was divided into 24 equal parts, each part covering 225 units (= 3°45') of the circumference. The twenty-four \*Jyā\* values as given by Varāhamihira,¹ Āryabhaṭa², Govindasvāmī³ and others for every increase of 3°45' are arranged in Table I. - [Previous: c8.166](https://indike.org/pramana/ins.science.bag-1979.c8.166) - [Next: c8.168](https://indike.org/pramana/ins.science.bag-1979.c8.168) - [Up: c8](https://indike.org/pramana/ins.science.bag-1979.c8) --- Source: [https://indike.org/pramana/ins.science.bag-1979.c8.167](https://indike.org/pramana/ins.science.bag-1979.c8.167) · Pramāṇa
