Compare the iterative sine approximation in Aryabhatiya with the modern Taylor series.

Aryabhatiya verse Ganitapada 12 gives a finite-difference recurrence for sine values at intervals of 225 minutes of arc. The modern Taylor expansion of sine around zero converges with cubic error. Aryabhata's table is accurate to roughly four decimal places at most arguments. See: Aryabhatiya Ganitapada 11-12, and Plofker H., "Mathematics in India" (primary reference 1).

Which datasets cover monsoon precipitation over the Western Ghats from 1980 onward?

Three datasets in the open datasets collection match: a daily gauge composite (1901-present, 21,915 days), a satellite re-analysis grid at 0.25 degrees (1979-present), and a station-level hourly archive (1990-present, 47 stations). DOI handles attached for citation. Want me to draft a comparative methodology section?

Request a physical book

If the item is held by a partner library and not available in our stacks or digital catalogue, we will request a physical copy on your behalf. Most loans are returned to you within two weeks; rare materials may require viewing on-site at our manuscript hall.

By submitting you agree to library borrowing rules. Late returns incur platform credit deductions. Rare and manuscript items are non-circulating: viewing slots will be offered in the manuscript hall instead.
