Abstract

The unpublished seventeenth-century Kannaḍa-language mathematical work Gaitagannai is transmitted in a single palm-leaf manuscript.  It was composed by Śaṅkaranārāyaṇa Jōisaru of Śṛṅgeri and is a karaṇa text cast as a commentary on the Vārṣikatantrasaṅgraha by Viddaṇācārya. Gaṇitagannaḍi's unique procedures for calculations wer introduced in an earlier paper in volume 8 (2020) of this journal.  In the present paper the procedures for calculations of the mean and true positions of planets are described.
