Vijayanandi
Vijayanandi or Vijayananda (c. 940, Benares (now Varanasi), India – c. 1010, India) was an Indian mathematician and astronomer who made contributions to trigonometry.
Son of Jayananda, the only known information is that he wrote a work called the Karanatilaka known only from an Arabic translation, Ghurrat al-Zijat , by al-Biruni.[1] There was however another astronomer named Vijayanandi who was referred to by Varahamihira (fl. c. 550) his Pañcasiddhāntikā (XVII, 62) for methods of computing the longitudes of Jupiter and Saturn.[2]
The Karanatilaka includes notes on the units of time, the longitudes of the sun and moon, computation of daylength, eclipse and other such topics.[3]
