The Hindu Raja of Cochin, Bhaskara Ravi Varman II ( 979 – 1021 ) gave them asylum.

Mention is made of Rayiran Chathan, the governor of Valluvanad, as a witness in the Jew's Copper Plate (" Joothasasanam ") of 1000 CE given to Joseph Rabban by Bhaskara Ravi Varma I, the Chera ( Kulasekhara ) King of Mahodayapuram. William Logan is of the opinion that Vellaattiri was also not directly under the Chera kings but enjoyed more freedom and rights than other chieftains under them.

Bhaskara Ravi Varman I ( 962-1019 CE ), the next ruler has immortalised himself in Kerala history with his Jewish Copper Plate grant of 1000 CE.

However, the King faced total defeat by the hands of Chola king Raja Raja Chola I. Raja Raja Chola I invaded Kulasekhara kingdom in 994-995 AD and destroyed the navy of Bhaskara Ravi Varman I in the famous Kandalur War.

Bhaskara II in the 12th century and Narayana Pandit in the 14th century both found general solutions to Pell's equation and other quadratic indeterminate equations.

The first general method for solving the Pell equation ( for all N ) was given by Bhaskara II in 1150, extending the methods of Brahmagupta.

* Bhaskara II, Indian mathematician

Bhaskara II ( 1114 – 1185 ) tried to solve the problem by defining ( in modern notation ).

The solution of the general Pell's equation would have to wait for Bhaskara II in c. 1150 CE.

The general method for solving the Pell equation given by Bhaskara II in 1150, namely the chakravala ( cyclic ) method, was also based on this identity.

1 ( so-called " Pell's equation ") was given by Bhaskara II.

Plofker writes that his texts were the most significant Sanskrit mathematics treatises after those of Bhaskara II, other than the Kerala school.

Bhāskara ( c. 600 – c. 680 ) ( commonly called Bhaskara I to avoid confusion with the 12th century mathematician Bhāskara II ) was a 7th century Indian mathematician, who was apparently the first to write numbers in the Hindu-Arabic decimal system with a circle for the zero, and who gave a unique and remarkable rational approximation of the sine function in his commentary on Aryabhata's work.

* Joseph Rabban-Was given copper plates of special grants from the Chera ruler Bhaskara Ravivarman II from Kerala.

According to Faizi, Lilavati was Bhaskara II ’ s daughter.

Bhaskara II studied Lilavati's horoscope and predicted that she would remain both childless and unmarried.

The auspicious moment for the wedding thus passed unnoticed leaving a devastated Bhaskara II.

Bhaskara II gives the value of pi as 22 / 7 in the book but suggest a more accurate ratio of 3927 / 1250 for use in astronomical calculations.

In the classical period of Indian mathematics ( 400 AD to 1200 AD ), important contributions were made by scholars like Aryabhata, Brahmagupta, and Bhaskara II.

Bhaskara Raya said that this was what would have happened to the sannyasi if he had prostrated to him.

Although Brahmagupta was familiar with the works of astronomers following the tradition of Aryabhatiya, it is not known if he was familiar with the work of Bhaskara I, a contemporary.

Govindaswamin who wrote commentary on Mahabhaskariya of Bhaskara I belonged to Kerala in Mahodayapuram.

In August 1984, when NTR was in the United States undergoing heart surgery, the state finance minister Nadendla Bhaskara Rao broke the party and formed the state government with the help of the opposition Congress ( I ).

It is to be noted that Bhatta Bhaskara ( probably in 10th century ) made the same statement in his commentary on Taittiriya Brahmana, another Hindu Veda.

He also learned Hindi grammar from Bhasha Bhaskara, to correct his Hindi pronunciation.

Kotla Vijaya Bhaskara Reddy ( 16 August 1920-27 September 2001 ) was the chief minister of the Indian state of Andhra Pradesh on two occasions, in 1983 and then from 1992 to 1994.

Bhaskara Deva, a Thakuri form Nuwakot, succeeded Vijayakama Deva and established Nuwakot-Thakuri rule.

After Bhaskara Deva, four kings of this line ruled over the country.

Bhaskara used it to give the solution x = 1766319049, y = 226153980 to the notorious N = 61 case.

From Kanyakumari he visited Madurai, where he met the Raja of Ramnad, Bhaskara Sethupathi, to whom he had a letter of introduction.

* 1150s – Bhaskara calculates the planetary mean motion, ellipses, first visibilities of the planets, the lunar crescent, the seasons, and the length of the Earth's revolution around the Sun to 9 decimal places.

When Nadendla Bhaskara Rao staged the infamous coup against NTR in August 1984, it was Chandrababu Naidu who helped his father-in-law's NTR regain power by rallying and parading all the MLA's before the President of India at Rashtrapati Bhavan.

He began playing a crucial role in the TDP after Nadendla Bhaskara Rao's coup.

* In Siddhanta Shiromani, Bhaskara developed spherical trigonometry along with a number of other trigonometric results.

Bhaskara derived a cyclic, chakravala method for solving indeterminate quadratic equations of the form ax² + bx + c = y. Bhaskara's method for finding the solutions of the problem Nx² + 1 = y² ( the so-called " Pell's equation ") is of considerable importance.

In particular Bhaskara seemed more interested in trigonometry for its own sake than his predecessors who saw it only as a tool for calculation.

Evidence suggests Bhaskara was acquainted with some ideas of differential calculus.
