Modelled in form on Lalla’s ŚDV (though with the addition of a chapter on the trigonometrical functions, jyotpatti and of another describing the seasons) the SŚB is the foremost text of the Brāhmapakṣa after the BSS. Bhāskara changes a few parameters minutely, repeats some of the improvements introduced by earlier astronomy such as the equation of time, and presents for the first time the formula for finding Sin (α + β),⁸¹ but the most impressive quality of the SŚB is its comprehensiveness. Commentaries on the SŚB were composed by, among others, Bhāskara himself (Mitākṣarā); by Lakṣmīdāsa in 1501 (Gaṇitatattvacintāmaṇi); by Gaṇeśa⁸² at Nandipura in Gujarāt in the early seventeenth century (Śiromaṇiprakāśa); by Nṛsiṃha⁸³ at Kāśī in 1621 (Vāsanāvārttika) and by Munīśvara⁸⁴ at Kāśī before 1638 (Marici). - [Previous: c4.s2.67](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.67) - [Next: c4.s2.69](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.69) - [Up: c4.s2](https://indike.org/pramana/ins.science.pingree-1981.c4.s2) ## Linked texts (3) - [Brāhmasphuṭasiddhānta](https://indike.org/pramana/in.astro.siddhanta.early.brahmasphutasiddhanta) — Brahmagupta, Sanskrit - [Śiṣyadhīvṛddhidatantra](https://indike.org/pramana/in.astro.siddhanta.early.sisyadhivrddhida) — Lalla, Sanskrit - [Siddhāntaśiromaṇi](https://indike.org/pramana/in.astro.siddhanta.early.siddhantasiromani) — Bhāskara II, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c4.s2.68](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.68) · Pramāṇa
