The Cubic Formula Tutorials of Tartaglia, Cardano and Vieta

The Cubic Formula Tutorials of Tartaglia, Cardano and Vieta

There are several formulas for solving the cubic equation. The earliest are usually credited to the sixteenth century mathematicians; del Ferro, Tartaglia and Cardano. Present day authors usually mention Tartaglia and Cardano, but del Ferro and Vieta also made important contributions. In this tutorial we choose to label our formulas with the names Tartaglia, Cardano, and Vieta. The Italian mathematicians Scipione del Ferro (1465–1526), Niccolò Tartaglia (1500–1557), Girolamo Cardano (1501–1576), Rafael Bombelli (1526-1572), and the French mathematician Franciscus Vieta (1540-1603), are credited with using a formula to calculating a real root of the depressed cubic equation . For convenience, we will include the possibility of the remaining two roots being complex, and thus begin a tutorial... Show More
