==Kamalakara==
Kamalakara's father was Nrsimha of Golagrama who was born in 1586. Two of Kamalakara's brothers were also astronomers or mathematicians: Divakara elder than Kamalakara born in 1606 and Ranganatha who was younger than Kamalakara.

<blockquote>
Kamalakara combined traditional Indian astronomy with Aristotelian physics and Ptolemaic astronomy as presented by Islamic scientists (especially Ulugh Beg). Following his family's tradition he wrote a commentary, Manorama, on Ganesa's Grahalaghava and, like his father, Nrsimha, another commentary on the Suryasiddhanta, called the Vasanabhasya ...<ref name="Andrew"/>
</blockquote>

Kamalakara's most famous work is Siddhanta-tattva-viveka which was completed in 1658. It deals with standard topics usually dealt with in Indian astronomy texts. The third chapter of the book is mathematically most interesting. In it Kamalakara has used the addition and subtraction theorems for the sine and the cosine to give trigonometric formulae for the sines and cosines of double, triple, quadruple and quintuple angles. In this treatise Kamalakara also makes frequent use of the place-value number system with Sanskrit numerals.

==Schools of mathematics in medieval India==
Historians of mathematics have identified several schools of mathematics that flourished in different parts of India during the 14th19th– centuries [[BCE|CE]]. It has also been noted that most of the mathematical activities during this period were concentrated in these schools.<ref name="Bag"/> The schools were at places identified by the following names:

* [[Jambusagaranagara]]
* [[Dadhigrama]] ([[Vidarbha]])
* [[Nandigrama]] ([[Maharashtra]])
* Parthapura
* Golagrama ([[Maharashtra]])
* [[Kerala school of astronomy and mathematics|Kerala]]
