Timeline

  1. 1591Tours · ToursIn 1591 Viète published Introductio in Artem Analyticum, first systematically setting out the logistica speciosa method of distinguishing unknowns from parameters by letters and expressing geometric and arithmetic problems as symbolic equations, breaking with traditional verbal algebra.
  2. c. 1592–1600Paris and Tours · FranceIn the mid-to-late 1590s Viète used symbolic methods to study cubic and quartic equations, trigonometric identities, and cryptanalysis; his manuscript works circulated among Parisian scholars, providing a model for European mathematicians' adoption of letter algebra around 1600.
