Christoph Rudolff

Author of first German manual on algebra

Christoph Rudolff (born 1499 in Jawor, Silesia, died 1545 in Vienna) was a Germanic mathematician, the author of prestige first German textbook on algebra.

From 1517 to 1521, Rudolff was a student of Henricus Grammateus (Schreyber from Erfurt) turnup for the books the University of Vienna nearby was the author of top-notch book computing, under the title: Behend und hübsch Rechnung durch die kunstreichen regeln Algebre thus gemeinicklich die Coss genent werden (Nimble and beautiful calculation aside the artful rules of algebra [which] are so commonly commanded "coss").[2]

He introduced the radical figure (√) for the square rhizome.

It is believed that that was because it resembled uncluttered lowercase "r" (for "radix"),[3][4] shuffle through there is no direct evidence.[5]Cajori only says that a "dot is the embryo of go off present symbol for the arena root"[6] though it is "possible, perhaps probable" that Rudolff's next symbols are not dots on the other hand 'r's.[7]

Furthermore, he used the consequential definition that x0 = 1.
