The word "unique" is appropriate there. See UniqueBharatveer 10:20, 10 July 2006 (UTC)

NPOV Message[edit]

I apologize, but the phrase "considered as the first text on calculus" smacks of NPOV. All of the references for this statement either have a regional slant, such as the Caniscus College reference [1] or the reference for the Government of Kerala [2], or directly or indirectly reference the Whish work [3]. Some more information on more recent interpretations of the Whish work would be helpful to your cause. Ggugvunt 19:15, 11 July 2006 (UTC)

Actually this text we are talking about is in Malayalam – a language spoken only by people in the small Indian state of Kerala. As such, all those who have done prime research on it, are Indians. Also to be taken to note, is the fact that only little is known even within India about the Kerala School. There are no references, whatsoever of any texts detailing about calculus prior to the Yuktibhasa. The only text in which a bit of calculus is used, is Bhaskara's Sidantha Siromani. But it doesnt go to the mathematical side, and only uses some differentials to prove a few astronomy theorems.
All in all, what I'm trying to convey, is that the article is in no way biased just because two of the four references given, are by Indians. It is indeed the first text on calculus. -- thunderboltza.k.a.Deepu Joseph |TALK04:49, 12 July 2006 (UTC)
Thank you for the extra information. I think that the page may even benefit from some of the comments you have given to justify your views, especially the lack of previous references. Keep in mind, though, there is evidence of some of the ideas in calculus from far before this - see How_Archimedes_used_infinitesimals for example. That being said, I admit it is a stretch to consider that a "calculus text" :). --—Preceding unsigned comment added by Ggugvunt (talkcontribs)
Yes, I am indeed aware of Archimedes, Aryabhatta, Manjula and Bhaskara all using infinitesimal values and basic ideas of calculus. But Yuktibasha, as you now agree, was the first text that actually details them (with proof too). I spent two entire days of my wiki-time researching up stuff on this page. Its always nice to receive criticism. Thank you. :-) -- thunderboltza.k.a.Deepu Joseph |TALK14:11, 12 July 2006 (UTC)

Sine rule not covered in respective article[edit]

Could someone document the rectangular argument at sine rule or provide them with the resources to do so? ᛭ LokiClock (talk) 16:23, 11 September 2011 (UTC)

3 centuries before James Gregory?[edit]

The date given for this treatise (16th century CE) is not consistent with being "three centuries" before James Gregory. Rob Burbidge (talk) 22:20, 6 May 2012 (UTC)

Correct, should be "century and a third". Now edited to give 1667 as date for Gregory. — Rgdboer (talk) 02:54, 24 November 2017 (UTC)


There are other forgeries. For instance, the Keralolpahti. — Preceding unsigned comment added by 2405:204:D182:24C1:6469:8001:AF6C:9208 (talk) 09:22, 23 November 2017 (UTC)
