@antopatriarca@mathstodon.xyz You are right about the thousand years (though for European mathematicians that knowledge had _arrived_ much less than a thousand years before—during the 11th century, if I recall correctly). I should have noted that I was mostly thinking of developments in mathematics _after the Classical Age_ of Europe. (As far as I know, some small and early steps towards trigonometry can be found in Ptolemy's works, but the substantial achievements are due to Indian mathematicians a few centuries later.) And yes, solving cubic equations was definitely the start of a long line of developments leading to the big extension of the subject matter of algebra in the 19th century. @davidsuculum@mathstodon.xyz
