Jyeṣṭhadeva, who lived from about 1500 to about 1575, was an astronomer and mathematician of the Kerala school of astronomy and mathematics founded by Madhava of Sangamagrama. A Nambudiri of the Parangngottu family, he was a pupil of Damodara and a younger contemporary of Nilakantha Somayaji, and Acyuta Piṣāraṭi was his pupil. He is best known as the author of the Yuktibhāṣā, a commentary in Malayalam on Nilakantha's Tantrasamgraha in which he gave complete proofs and rationales for its statements, which was unusual for traditional Indian mathematicians of his time. The Yuktibhāṣā is now believed to contain derivations of Taylor and infinite series expansions for certain trigonometric functions. He also wrote Drk-karana, a treatise on astronomical observations.
