write the contribution of sridharacharya in mathematics field
Answers
Answer:
Sridharacharya , highly esteemed Hindu mathematician who wrote several treatises on the two major fields of Indian mathematics, pati-ganita (“mathematics of procedures,” or algorithms) and bijaganita (“mathematics of seeds,” or equations).
Very little is known about Sreedhar’s life. Some scholars believe that he was born in Bengal, while others believe that he was born in South India. All three of Shridhar’s extant works—the partially preserved Patiganita, Ganitasara (“Essence of Mathematics”), and Ganitapanchavimashi (“Mathematics in 25 Verses”)—belong to pati-ganita, but, according to Bhaskara II (1114–c. 1185), he wrote at least one book on bijaganita.
Patiganita consists of versified mathematical rules, without proofs, and examples arranged under the two headings parikarman (“basic operations”) and vyavahara (applied or “procedural mathematics”). The first part treats arithmetic operations (including the calculation of squares, square roots, cubes, and cubic roots) for both integers and fractions, reductions of fractions, and proportions. The second part presents mixture problems and various series before it breaks off in the midst of rules for plane figures. The topics of the remaining sections are ditches, brick piling, timber sawing, heaped-up grain, shadows, and zero, according to the table of contents given
