c4.s4.t2.8

Besides *Veṇvāroha* which deals with an accurate method of calculating the exact positions of the moon Mādhava is well-known for his work¹ on trigonometry and on infinite series with correct determination of the value of π. Nīlakaṇṭha quotes profusely Mādhava's name and says that he has used Mādhava's theorems in his (*Āryabhaṭīya*) *bhāṣya*. In one place he quotes a verse attributing it to Mādhava and admits that he has heard it from an astrologer while travelling in North Kerala². This suggests that Mādhava besides *Veṇvāroha* might have composed other works which though extinct at present became popular throughout Kerala. Mādhava is largely quoted in later Malayalam works namely, the *Yukti-bhāṣā* of Jyeṣṭhadeva, *Kriyakramakarī*, a commentary on the *Līlāvatī* etc.
