His mathematical astronomy text Siddhanta Shiromani is written in two parts: the first part on mathematical astronomy and the second part on the sphere. The twelve chapters of the first part cover topics such as: Mean longitudes of the planets. True longitudes of the planets. The three problems of diurnal rotation. Diurnal motion refers to the ...
Another class of numbers Kaprekar described are Kaprekar numbers. [10] A Kaprekar number is a positive integer with the property that if it is squared, then its representation can be partitioned into two positive integer parts whose sum is equal to the original number (e.g. 45, since 45 2 =2025, and 20+25=45, also 9, 55, 99 etc.)
Narayana's other major works contain a variety of mathematical developments, including a rule to calculate approximate values of square roots, investigations into the second order indeterminate equation nq 2 + 1 = p 2 (Pell's equation), solutions of indeterminate higher-order equations, mathematical operations with zero, several geometrical ...
