Calculate and give out the latitude and also the colatitude of the place.² Authorship and appreciation of the work: 26. This Aryabhata-karma-nibandha ("a compendium of astronomical processes based on the teachings of Aryabhata I"), which has clear expressions and simple methods (of calculation) and which can be comprehended even by those with lesser intellect, is written by Bhaskara after full deliberation. 27.

See supra, p. 45-46.
- Assuming the obliquity of the ecliptic to be 23°30', the required
